I mean it is 35k, so it makes sense on how its this good. Don't give the devs ideas to do a stupid decision bro, the tower is fine at the moment (I'm not biased, I genuinely think its fine)
I think engi is a bit better and a bit worse then gatling not only being engi has 3k dps but it can be usedin early mid and late, but gatling gun is more useful for dangerous waves like hidden boss, f-jesters, and it can help in hard core so I'd put it above engi even though it has less dps its still more useful and flexible then engi. 2000 dps on a single enemy is op as hell, and im glad its a coin tower.("no one can survive alone")
