A few things about why this post is bad :

1. LAVs have more base HP than Dropships ... but Dropships have twice as many slots. Effectively what this means is that a fitted Dropship will easily be able to tank more than anything an LAV could. Being that the LAV is restricted to 2 high / 1 low and 1 High / 2 Low what you'll see is that you cant simultaneously fit an extender, repper, and a resist onto an LAVs most desirable stat (Gallente Armor, Caldari Shield) at the same time. Dropships don't have this limitation.

2. You bring up Invincible Murder Taxis but forget that a lot of the reason they're invincible to begin with is because they have an insane base resistance on top of great fitting options. Comparing the new paradigm of vehicles to what we see in current LAVs is flawed logic. Even if the next LAVs had the exact same health as the current LLAVs they'd still be no where near as effective at tanking the same amount of damage thanks to changes to the modules / slot layout / lack of resistance.

3. L. A. V. - Light ATTACK Vehicle. Believe it or not there was a point in closed beta where this acronym was an accurate description of what the LAV was on the battlefield, and Im not referring to the invincible murder taxis we saw in Uprising. There was a time where people would willingly jump into an LAV fitted with Missile turrets and be able to effectively rack up a fair amount of kills because the LAV + Turret Gunner was an effective glass cannon on the field. With the changes to Missile Turrets and the decrease in range of Blaster Turrets this stopped being the case and they became, as you implied, strictly Murder Taxi / Transport vehicles. In my eyes, and clearly in the eyes of CCP, this is something worth changing.

4. Off the top of my head though I could see a Weaponless Dropship as something one could use while coordinating with squad members for transportation across a large map. The fact that it's weaponless would mean that you could fit a CRU or Scanning Modules without worrying about needing CPU/PG extenders in order to do so while also potentially increasing the overall tankiness of the vehicle. It'll be more niche and less commonly seen no doubt but it's something that could potentially be useful when there's a fair bit of communication used.

Sooooo....Im pretty deep into vehicles (hav 5)..I skimmed over the 33 pages in this thread and didnt notice if vehicle drivers will get refunded the SP..I may not want anything to do with vehicles after all this.. atleast give us the choice..

HAV 5, meaning.................................. what?
