Now, first off. That migth just be my opinion, but i just pretend its the word of god:
I think accid runner is worse then normal runner if you take away the big boom. I jokingly say “accid runner is a crutch” for a reason. It is easy to play, but it has not the same potential as normal runny. That is more a burn toward accid runner mains then anything but ehh. If your such a main you go acid runner as greeno, you dont get my pitty.
Real talk now:
Acid runner is for what it is fairly strong, i agree. The Giant boom cloud is way too often unearned. Something like that should be a reward for players that do well, not something the ssd runner in the hive can achive.
Basic rule of game design is always: “Reward players for doing well”
That is often one ciritcal point to make something fun to figth gainst, and more importantly fun to do. A reward that is earnd, always feels better then something you are gifted.
So, how would one make this more fun and fair?
Against SSD Acid runners:
Basicly the two suggestions of @ihatethisengine are perfect. But i would not say to fully remove passive generation. Rather give it a cap, so that you can generate up to 300 accid over time. If you reach that ammount regeneration wont give you more.
That for 1) prevents acid runners to afk in hive until they get a 1k boom. 2) Still allow not good players to get some accid for melting stuff and little boom.
Basicly every player can get some form of explosion, but only good ones get the big one that can wipe the front. Giving everyone a chance to try and blew yourself up, and rewarding good players. Also that way you can get accid to melt stuff without needing to be good, wich is like the ultimate thing for bad combat players. Supporting. Like i always do
But jokes aside, it is very important to leave a way for players that arent that good yet to gain it somewhat. You want players to go “Wow, that can go even larger? I want to try and do that” not “I cant even manage to get it in small, why should i try for the big one”. And you cant get the first one, if you dont give them a taste of whats to come. And no, seeing others do it doesnt count. You need to feel it, do it yourself.
To adress @Lichen 's point of "farming marines for accid":
Easiest way that could be fixed is remove accid gain from marines that already have accid on them.
This would also encourage players to play more like this strain feels like its supposed to be. A hit and run role. Where you dont try to attack one target a lot, but a lot of targets often. Basicly more atrition focused, being that one good acid runner can easily make sure a small group of marines runs out of medicin really fast. So why slash more the same guy that aleady has KD in them. Slash the other guys so the medic has to use up more.
Big problem i see there would be how it would interact with spitter accid. Like, would you get a gain from people coverd in spitter acid? Would it be overridden with runney acid? If not, could that be a loop hole to farm accid again? But thats mainly because i dont know how they both interact.
Only one slash is too little, but i cant imagine if there is an easy way to code it otherwise. Like, only gaining accid the first three slash to a marine. And resetting that somehow. Maybe it is easy though, i dont know coding in beyond very well.
Making it more obivious
There is already the pro strat of going far away when you go boom so most marines dont hear you and then hiding behind a corner and jumping out just before you go boom.
Two problems
1 Its a good reward for players that are abel to time the explosion rigth and are good at positioning. So cant make doing that too hard.
2 People often dont realize the acid runner is still… on? So consident warning its going of would be better then just a warning once it starts. Yes the brigth green helps, but marines are often to dumb. It should be loud and proud telling the world its about to blow itself the fuck up.
1 means you cant make its signal too obvious. 2 means it needs to be somewhat obvious still. So either a consitend beeping like a bomb thats about to go off thats getting faster. Or the runner just fucking blinks green.
Now, the last point migth already be in the game, with the beeping sound. But i am already senile despite my jung age. So forgive me that fauxpas.
TL;DR
Accid runner aint that OP.
Maybe need some tweeking.
Normal runner gang FORLIFE!!!
