i said it on the last thread i saw you, but i think it'll mostly be splattershot variants with one roller
a roller on the back where no one is around, to cover up dry ground and enemy ink
someone vaguely near the area of the roller to both scout the flank and protect them from danger (since the rollers are in practicality an ambush melee weapon since it's easy to get out of flicking range)
two players on the front lines, away from the flanks,who attack the opposing team head on, marking their territory with ink after fights
i don't think there'll be a charger/rifle user in the back because it's a really niche weapon. the weapon gets the job done, but it's the exact opposite of flexible, and with a max of 4 players per team, you'll want weapons with as much broad use as possible. i think it'll be good in turf war and splat zone pubs, but not higher level competitive gameplay
these are just my own thoughts on how it would work. the game is really, really unique, and it's not even out, so we can't take the meta from another game and make realistic comparisons and guesses... and to be honest, that's what makes me so excited about the game
