In their current form, scuttlebots are less threatening than even Chromas. I know Boswick is a man of peace and shrubbery, but it's time to let the pendulum swing towards Ian's chaos and bitter tears.
I suggest:
T1: Basically like they are now. I don't hate noobs that much
T2: Fire a single slow elemental bullet with long range similar to T2 Kats/T1 puppies
T3: Fire a volley of three slow elemental bullets with long range, again similar to T3 Kats/T2 puppies
Also put the T3 scuttles into IMF, especially the boss stage with the twins. The current scuttles in the boss fight aren't much more than decoration.
I think they buffed them a little in the last patch. I dont know why but i find them more threatining than before O_o
But they are still trash, they should give their attack a little bit more range
