I am curious, are you sure you want to do a T1-P/C fight against 2-4 other people? T1-P/C is tough enough in a one v. one, stacking the deck against yourself, leaves you little chance to win because your attacks/defense have to be divided against 2-4 people which means you cannot attack or defend everything. And using T1 rules will constrain your ability to charge your skills while allowing your opponents the ability to charge their attacks by taking turns in their attack rotations. 

And what do you mean by GM? You stated a T1-P/C fight which means you may draw some very heavy hitters against you since powered characters mean just about anything.
