Really good idea, vehicles currently have weapon specific amplifiers so I dare say it wouldnt be a big deal to make Dropsuit variants too.

So your suggestion is make weapon type specific damage mods that are exactly how they used to be except only half for laser weapons? So no one complained about other weapons killing too fast with damage mods?

The fact is that unlike your CODs or Battlefields, in Dust everything you use is consumable. It costs you ISK or Aurum, and in that sense it is an investment. People don't like seeing their investments melt near instantly. It makes sense that because of this Dust also has a higher TTK than your typical CODs or Battlefields. It doesn't mean it's going to take 40 headshots to kill someone, that is ridiculous even for a hyperbole. The game will still be fast, worry not. I've been part of highly competitive shooters where it would take nearly a full clip from an assault rifle to kill someone and the game was still extremely fast paced. It just gives the player a chance to react, make them feel like if they die and lost their investment it was their own fault and make it clearly visible what they need to do to prevent such a death in the future.

And to be honest, I'm not a fan of the new Commando's bonus or even the new proficiency changes because they still increase damage. Both of these need to change to something non-damage related in my opinion.

The new skill bonus for commandos which give more damage for a certain weapon type woulda have stacked horribly together with stacked damage mods. CCP didnt nerfed damage mods because the TTK is too low. No they nerfed them so that you can achieve the same damage after the patch with the new suits and thats it. Its the same stupid logic with the logis. Nerf all equipment and give each logi a specific bonus so that they work like they used to be. This nonesense needs to stop right now. Its taking the fast pace theme of gunfights out of the game. I dont want to wait a minute to restock ammo from my crappy nanohive, i dont want to shot a guy 40 times in the head till he drops and i certainly dont want to sit 5m next to a heavy to rep him knowing that i will very likely die to grenade spam.

Back to damage mods and how we can solve the AV issue:
the easiest way to solve this would be to make sub categorys for damage mods. Something like this:

-Light complex laser damage mod. +5% to light laser weapon damage (scrambler/laser rifles)
-Light complex missile damage mod. +10% to light missile weapons damage (swarms)
-Heavy complex hybrid damage mod. +10% to heavy hybrid weapon damage (forgegun)

Doing this will bypass the AV issue and still give the commando a reason to be used. I picked this idea up cause vehicles have aswell seperate damage mods depending if they use missiles, blasters or railguns. So why not adopt this to infantry gameplay?
