Orleans, bro, relaaax Costs us nothing to answer a question or two.
Reading between the lines -
Persistent items will follow the Team Fortress Two model. They allow new abilities and buffs but are carefully balanced so that my first hour as a Heavy I can completely destroy your 1000 hour Pyro.
As Trigeminal says, persistent items are are point-based, and should not represent a ceiling to play. In tournament play I think points can also be used to advance your character or pull someone else back a rung, so you have a nice strategic choice here.
Camping a skirmish will be far less effective on a point basis than playing a new game, as there will be a limited number of points available in any given game.
