Multiplayer practice tool.

So, why can't I enter the practice tool with a friend? Or perhaps make a practice tool custom game lobby? If it's a question of who should control the cheats the easiest solution is to give it to the party leader, or room owner the the case of custom games. The application in testing mechanics and practicing scenarios is nearly unlimited, especially if there can be teams and spectators. Additional abilities aren't even needed. And for the less progress or competitively minded, it creates a place where the rules can be made different. Make towers invincible, lock lvls at one and play to 5 kills anyone?
