In S1, definitely. Occasionally I'm playing a game and then the entire map is just the other team's color now. More rarely I'll encounter someone with more advanced hacks (throwing splat or burst bombs every frame, etc) but generally it's just... the map is pink now, good luck. The most annoying part though is that you might actually start to get an advantage back, you have a perimeter of ink around you, and then it'll all go back to the other team's color again. It's even worse in splat zones since paint is the literal objective. (Not turf war though. Not because it wouldn't be broken but because i haven't encountered hackers in turf. There's no incentive to hack ig)
this is how they should buff sprinkler. make it do this, then it'll be the strongest sub in the game and won't ruin any more kits
