I don't really have as many issues with them as some others, but the annoying thing in this game (im not sure if due to lag or tick rate or what) is that sometimes enemies' shots hit you when you've moved out of the way, e.g. Being sniped around a corner. My theory is that the tick rate is part of why the tri feels insane, since if you consider the fact that people are getting hit by things they avoided due to whatever factors, those same factors would make a bucket that hits a wide area with no falloff damage even more powerful than normal. I don't really have any proof, but that's just my theory on part of why it feels worse to fight against than the first game.
I don't really use it but I have trouble with it from time to time as a splash-o-matic main since it shoots at about the same range you get hit at, but that's probably to be expected.
