Sure, but then roller originally came with suction bomb.Splattershot came with burst bombs in the original too. Same with splat charger and splat bombs; only their specials are different. Though this special is kind of disgusting for the splat charger since it gives you a nice tool to help out in charger duels.
Can't wait to see two chargers bust out lasers against each other. It's going to be like Ghostbusters.
