"many very good players will actually snap around and kill you"
Assuming I somehow have never faced a good player and avoided this anyway, how are they going to y-snap on you if you're already three strokes in and kill? The only guns I can see doing that are Blasters and a Gal and even then, it's not like you have to stand perfectly still with the Inkbrush to hit someone with it. You also wouldn't pick a fight with someone who clearly sees you running up to them. Pick your battles like with any other weapon.
"You aren't camping **** with an Inkbrush."
I'm not sure why I would camp asterisks with anything, but that's always my main goal in either SZ or TC (if we're not getting pushed back to hell, which is a possibility regardless of weapon choice, naturally), camp the enemy side. Assuming my teammates aren't brain dead, there are 3 people who can easily watch the zone. Meanwhile I can sweep a whole area with my paint in no time at all and easily hold it down for a decent period of time. No one's going to perfectly guess where I'm hiding every time in a large zone, and they can't afford to lose ground by only painting pathways out of spawn - that makes them easier to kill in general. In the event you get caught in a bad scenario, unless you're already stuck or trap yourself in a hallway or have your back against the wall (or run out of paint), you can usually get behind cover quickly enough to funnel them in where you want them or make them realize there's no point in playing tag with you, because now you're a distraction.
"You'll never beat any decent player in a direct 1v1."
Why would I go out of my way to directly 1v1 people? Like I said, pick your battles - any player should go out of there way not to have direct 1v1s. You could be the best shot in the world but your chances of winning encounters are gonna go through the roof if the enemy isn't looking at you. Like I said, you just pick your battles like you do with any other weapon. Even if someone y-snaps, if I'm already 2-3 strokes in and not standing still, if you don't have a Blaster or a Gal, how are you going to take me down any faster? It's not like you shooting a brush user is going to stop them mashing ZR. The other person could run away, but I'm not going to chase after them, that's suicide. Of course if you have more than one person in that situation, that's dicey, but I repeat, pick your battles.
"Support"
Fastest weapon out of the gate at start and can easily solo cap SZ or start getting the push ready by painting ahead in TC.
In general has the fastest ground control out of any weapon due to the flick - you can regain any lost territory without support, and have the speed to run away from most bad situation (tho' of course you'll need the required secondary power of situational awareness and knowing where not to be in general for this to work).
Can easily ignore the objective and loop the map to the enemy side, capture it all solo, and then control that side of the map for as long as you can stay alive. Your enemies are now slowed and you can still pick them off one by one, essentially freeing up the entire map for your team. Granted, the Inkbrush is the only weapon with it's "line" so you could easily anticipate it coming, but you don't have the speed to keep up with it, and you don't have the time to wait and see if it's going to do anything or not. Either someone chases it down, meaning one less player working towards the objective, ignore it, leaving your rear exposed to easy coverage, or you try to juggle this potential "between a rock and a hard place" situation, where you are being gunned down with a potential back death coming your way. Even if a brush did trade in that situation, there's no way he's going to momentarily ignore the firefight behind him, take damage from brush, gun him down, and then going back to shooting them. Of course, your team has to be competent for this to happen, but I think that's to be expected for the "support" to matter.
