I think they decided that specials were too strong in the first game and decided to tone them down for this one.Oh, cool. Well at least there's that I guess.
I'm not used to the specials yet. The seem...not as good as Splatoon 1? But maybe that's just because Inkzooka, Bubble and Kraken were so OP. The curling bomb launcher is awesome, though, and makes it even harder for me to stop using the Aerospraty MG.
