City of Heroes will allow you to do just that, and it's a set that players have been waiting on for what seems like half of forever. And if you're wondering what the set can actually do, it's probably a fine time to take a look at the newest issue of the Intrepid Informer, showing off the set's powers and the new mechanics involved.
The core of Water Blasting is a stacking buff known as Tidal Power. Certain powers build Tidal Power, certain others consume it, and some build the buff if you're at less than maximum capacity but consume it otherwise. The powers involve several knockdowns as well as a heal, a short-range defensive burst, and an assured AoE knockdown when played correctly. Take a look at the full rundown and start planning on your upcoming squirt gun character (Super Soaker being the obvious choice)!
