Assault needs to be returned to how it was in the BF3 and BF4 era. Practically everyone bought this game because they wanted those games.
Support now is the class of the sweatlord. And why not? Unlimited ammo AND health regen AND bonus resistances? It's almost like they made that class for the turbo sweatlords.
All GL grenades types should be available to both. The penetrating stun needs to be changes to a sticky delayed stun (so you can use it, get your weapon out, THEN engage) Assault rifles just about need a buff across the board, though I say give assault to engi, PDW to support, and LMG to Assault. I mean you're ASSAULTING for goodness sake, while support is supposed to be SUPPORTING. Instead it's supports who never use anything but mammoth and another gadget they will never touch, they will almost never rez, they won't pay attention to their dang map to see the 20 people around them spamming "I NEED AMMO" Neebs. The unlock through points buffs need to be turned into just regular all the time buffs with the actives being turned into another passive or maybe just plain removing it would be better. The fire shotgun needs to be turned into just a shotgun that you can choose the rounds you use instead of only fire.
Honestly those passives need a ground up rework. Give assault a real suppression mechanic like we had in the old games. Give them a helmet that lowers sniper headshot damage to 95 instead of ohko. Give them a lead the way passive that gives allies advancing towards them a MS buff or maybe a damage reduction buff for being behind them (from point of attackers view) or something like that to encourage them to actually play with their team AND make their team appreciate them a bit more. Bam one passive tree down. Second passive tree is related to supplying ammo. A buff to resupplying offensive gadgets, a buff that restocks allies over their ammo limit (not including gadgets) and then third is they can have 2 ammo packs out at a time instead of 1. Are this perfect? Nah, but 100000000000% better than what we have now.
I don't think you can talk about fixing the assault without also talking about fixing support. They shouldn't have been combined into one class. I'm sure that if we could review genuine statistics, we would see support currently being the highest picked, with assault being the lowest.
Ways to fix it without this kind of rework? Ehh... Make the epi-pen not suck, again open all GL options, same change to stun gun thing, Cap speed needs to be 1.5 if it isn't, sure doesn't feel like 1.5. Passives still just need completely redone. Considering the only 3 passives i know in the game are engi get more rocket, snippy can see boom rocks, and snippy can headshot to death... I have no idea. The passives and actives in this game just reak of CoD and could honestly be deleted with probably no one noticing a bit of difference aside from those rockets. Same change to bolty boomstick. Suppression back for ALL classes.
Honestly if I could just have LADDER instead of epipen I would be far happier. Ladder is actually kind of useful, kind of fun, and stupid in a good way.
