The more mobs you fight and the more damage you deal, the more mana will return.

Advantages:

1. No "hey that's my aggro!" between players.
2. Warriors will be forced to attack (This is what true warriors are). No mana return if we spam attack through air Lol.
3. Distance between PVPers would not be an issue anymore. So Rogues, let warriors come to you.
4. Right now, mobs that dies easily won't be able to give back your mana.
Self-buff would solve this.


Mana return should be directly proportional to the damage dealt by Warriors (Anyway Warriors don't do that much damage compared to
the other 2 classes, so this is feasible).
