I posted my idea in a thread a while back about having multiple sub weapons in online battles like you can in single player mode. An idea for a sub weapon is a gravity bomb like a splat bomb. It creates a small black hole about the same size of a splat bomb explosion that sucks in any enemy and enemy ink caught in the singularity. Of course there's a delay so enemy's can escape. And you get fare warning just like with an ink strike.
