My suggestions:
All right click charge weapons: Increase speed of charge.
Reasoning: The damage output/utility is not worth not only the time spent charging, but hoping that your opponent will actually be visible at the exact moment it hits 100%, seeing how it's not an on-release thing. Which, it should also be changed to that too.
Sniper: Remove the slowdown on charge.
Reasoning: Sniper is taken for it's skill based damage and doubles as a mobility weapon. Completely immobilizing yourself is not worth taking the shield off for a few more seconds.
The slowdown plus the rate it charges makes the charge shot probably the weakest strategy in the game. Lets say, even with the charge time, the slowdown, and the fact that you have to hope to god you're aiming at them the exact moment you hit 100% (with the only indication being a center print), and for whatever reason that works and you're not dead. You knocked their shield off for a few more seconds. What are you going to do about it? Any other weapon could've possibly outright killed them 150 to 0 in the time it took you to land that shot. Or maybe not, maybe they only took 25 health damage and regenerated that shield. So what are you going to do now that their shield is down for a bit longer? Use your secondary? With the slowdown, you were probably unable to put yourself into a position you could engage from, so they're just going to hide for longer. Or maybe not. They might just kill you. It's more worth it to just boost yourself out from cover for some speed, and hit them two or three times for a kill. Or even two for that 50 health damage. You can probably do two shots before it even finishes charging. And if their shield comes back up, just shoot them again.
Flamethrower: Remove or replace airblast entirely.
Reasoning: I understand some weapons are supposed to be better against certain weapons and all. But this completely nullifies warhead launcher with zero level of skill. Yet, against shotguns or any rapid fire weapon, it's completely useless. It's basically a 1 HP shield that regenerates faster than your 50 HP shield.
Burn Mortar and Saw Tomahawk: Increase projectile speed.
Reasoning: These weapons are entirely based on "Wow I certainly hope they accidentally run into this projectile" at any range that super shotgun can't already just turn someone into soup. Obviously it doesn't need to be 'as fast as other weapons' or not even 'almost as fast as other weapons'. They just need to be usable.
Chaingun: Somewhat reduce the rate at which overheat occurs, or give it a secondary ability.
Reasoning: Right now, it's worse than sawblade rifle because it's now punishable without offering any utility. Where sawblade is less punishable due to it's neverending fire, and the utility of bouncing projectiles AND FEAR ITSELF. It can probably still deal more reliable damage at a range, but that quickly ends.
Gas Op Rifle: Change it's right click ability
Reasoning: It's already almost only useful for it's mobility. And then it just got more. This is Overwatch levels of madness.
