we all know that the ads is the most used ds in the game. Ds are mostly used in the beginning of each match

Here are ways to improve both in different areas.

Dropships

1. Give bonus to turrets on dropships to make them better at dealing damage and suppressing enemy while deploying/extracting friendlies from area to area.
Dropships REALLY do not need this, in essence this is what the assault dropship is for. Just my opinion.

2. Slightly increase speed and maneuverability to make them better fliers. Buff just enough that they are still under assault dropships.
While I do not disagree, they need to be anything but close. There has to be a legitimate difference in "feel" between the ships

3. Increase Myron shields (it's too weak)
What?? My Myron is practically indestructible. I always run with a gunner and we can take swarm launchers head on without worry.

4. Give more bonus wp for dropping/picking people up. It's one reason most don't use them the whole game. It's not worth it. There are better ways to get more wp
I agree with you whole heartily

5. Give a racial bonus.
Gallente- equip an afterburner and get 10% more passive speed and maneuverability.
Caldari- equip 2 or more extenders and get 10% more hp (shield)
I wouldn't be against a bonus, but these bonuses seem out of place. Perhaps Myron can get Shield Regulator Module Efficiency bonus and Grimsnes can get Armor Repair Module Efficiency bonus?

6. Allow only assault, combat, rail, and scrambler rifles to shoot when not in gunner seats. Add a skill in these weapons to allow ability to fire out of ship.
*Shrug*

Assault dropships

1. Remove the 2 passenger seats and only leave the 3 gunner seats. No one really like being in a dropships for so long, especially when you don't do anything.
I use the extra seats to transport 2 extra people at a time, while I have a gunner. These can be HMG users, scouts, snipers or Forge Gunners to help with whatever task my ADS is taking off to perform.

2. Racial bonus
Gallente- 5% damage to weapons (so that it could be used more as an option with missiles which is currently preferred on Python)
Caldari- resistance to blasters 10% (low shield hp lets blasters CHEW you up)
Room for debate about modifying current bonuses, for sure.

STD dropships are fine. They're far more tanky than ADSs. They have enough firepower to act as gunships if wanted. They're fast enough to make escapes and do most the maneuvers ADSs can do (though not as quick).

The biggest problem with DSs is that no one utilizes them to their fullest capability. That's a problem with the community, not the DSs themselves. You can easily pull about as many WPs in the sky as you can on the ground (maybe not top 3, but up there), so long as your team makes use of you.
