It definitely has affected me.
I forgot about the people who put beacons on spawn, follow you painting the same turf, paint the water, ignore the main place in the level that needs holding to win in favour of that tiny little corner that might net you 1%, give away your position by firing everywhere when your sneaking up on someone, bust out an ink strike in the wide open to get killed instantly.
I've seen all of that this splatfest. Repetitively.
And yet I'm still playing when I reached king a while ago.
I have an issue
On another note. I can't wait for the fresh squiffer. I'm not a fan of either special on the current builds. Don't mind the subs, but would like something to pressure with to help with positioning. Kraken is pretty decent to give you a free re-position too.
