You're the one who's mixing the roles. The HAV's we got now does what it's supposed to: decent DPS, decent speed, tank The tech 2 hulls will nerf one of these, buff another, and keep one the same:

Marauder- high tank, **** speed, decent DPS.

BO- High mobility, **** DPS, decent tank

Enforcer- High DPS, **** tank, decent mobility

That statement could mean several different things. elaborate.

The problem is basically that CCP's trying to do pretty much everything, with everything.

Make large turrets "AV Turrets" and small turrets "AP turrets". These changes are keeping in mind the upcoming turret ammo.

What changes for large turrets:

-Missiles and railguns lose their splash
-Missiles get more missiles per salvo, higher damage per missile
-Railguns get longer initial spool time, higher direct damage
-Blaster RoF is reduced to 120RPM (2RPS)
-Blaster damage is increased accordingly (around 3-4x) to compensate
-Blaster should overheat in the same amount of time as currently

Mostly these are changes to the blaster, obviously because currently as a large turret it's the most devastating against infantry. With the RoF nerf, infantry should essentially be able to run past a tank without being killed, BUT if they stand still or if the tanker is exceptionally accurate, they're goners because bullets will deal massive damage.

And without splash damage, railguns and missiles will lose much of their AP capabilities. Still possible, but difficult.

Now, as for AP (small turrets):

-Railguns need more splash, more direct/splash damage, slower overheat
-Blasters need a tad more range, and slower overheat
-Missiles should stay the same but perhaps lower the RoF to make the ammo feel like it lasts longer.

Essentially buffing railguns up so they actually have a chance against blasters and missiles in terms of AI.

With these changes, instead of small and large turret slots tankers will get two AP and 1 AV turret slot. Make it clear from the outset what the tank driver's role is, and that it is the job of his passengers/crew to support with anti-personnel small turrets.

Someone phrased this best, but the new roles of HAVs are what was described as 2 min / sporadic battering rams with how active modules are going to change. So HAV pilot main role is essentially going to function as stall breakers.

I agree that HAVs don't seem to have a good role.

I'm not sure what that role should be though. As an infantryman I'm not keen on the invincible rolling death machine that a few of the tank players advocate for as it doesn't do anything that infantry can't already do (although it does it better while being a bigger target).

Dropships and LAVs have obvious transport roles.
A APC type troop carrier would have obvious roles in transporting, spawning, healing, supplying, boosting infantry.
Fighters would be anti-dropships vehicles (dropships would need more impact to make them worthwhile).
Bombers would probably be large area denial and/or anti-ground vehicles.

But what about tanks?
-"Breaking through enemy defences" sounds like destroying installations to me but installations don't play a large part in the games at the moment and blowing them up sounds like a terribly boring activity.
-"Supporting infantry" tends to mean killing enemy infantry (or scaring them so they hide) which is a role I would prefer to give to heavies and heavy weapons.
-"Destroying other vehicles" is a fine role but not terribly useful with the small imparct of LAVs of Dropships at the moment. Without other roles tanks killing tanks is a closed system.

Perhaps if turrets were serious threats to infantry?
If turrets flipped with null canons (or some other area control panel) instead of individually then disabling them would help infantry take an area.
If the turrets couldn't be permanently destroyed, just temporarily disabled, then that might give tanks more to do.

Just brainstorming.

NAME: % AV / % AP

Large Blaster: 80% / 20%
Large Missile: 90% / 10%
Large Railgun 90% / 10%

Small Blaster: 20% / 80%
Small Missile: 25% / 75%
Small Railgun: 40% / 60%

I like it, BUT this could be negated by the 'future tech' argument.

Maybe projectile dispersion should increase based on whether or not you're taking damage. Taking more damage: bigger, unfocused reticle. Therefore the longer the tank withstands a pounding from AV, the more ineffective it gets in combat.

How the reticle is restored to maximum potential is something to be discussed too though. Should it be based on the current percentage of HP the tank has, or should accuracy keep diminishing until the tank returns to 100% armour? Explanation could be repair nanites focus on survivability/mobility first and offensive capability last.

And my bad with the percentages. To be honest all I wanted to show was whether the turret in question was better in AV or AP.

You had me on the turrets until you talked about , " how the armor repairer shouldn't repair the turrets ." Then they should have a turret repairer ??? One more thing that you can't place on your tank due to the computer and programming capacity and also the slot limits . The turrets damaging effecting the performing overall makes since but they should be repairable and WITHOUT help from SQUAD MATES

The damage meter automatically goes down over time

I did but " over time " ??? How do you define that ???? Is it like if you had your shields knocked out and you don't have a charger mod or shield booster available so it's like , tic ... tock ... tic , aw come on already ???? The way you had the scenario going made it seem like if you didn't have support and you were to encounter another tank or swarms or even a few forge gunners and troops with av's ( just the luck you need and that can happen even now to someone who doesn't have the RIGHT mods ) then you will be dead in a heartbeat ???? It just seemed like there was no way that you had given to speed up this process without personal to support you .

How would an turret repair mod be situational if this is something that you have suggested ???? ( i.e. turret damage ) Shouldn't a tank user have a way to repair something that effects his or her tank's performance ??? Shouldn't that become an option ...???... just like your proposal ??? A turret is a part of a tank and actually one of the MAIN parts of it because it produces offence and defense and without the turrets , what is it then ????

They are made of paper mache as you have stated . Try using a SICA or a SOMA even with advance turrets and mods and see how far that will get you . THEY ARE HORRIABLE and are not worthy of being called tanks . But I guess that's why they are re-working the vehicles .

I'm going to stop commenting on this topic because clearly you don't understand me.

AV TANK: railgun. INFANTRY TANK: Blaster. seems simple to me.
