First of all, you should've made this a poll.

To start things off, I find that adding water to levels in multiplayer adds a little bit more needed strategy, and strategy is always more fun than bouncing around shooting. However, if the whole level is underwater, this takes away the gameplay normally given above, and it eventually gets very irritating when you can't go on your favoured landscape. So I'd say I'm a little between the idea. Nice to see your back here, too, after all this time.
