Tag some code onto the MA crit buffs to make them useless against other non-npc characters except for the MA themself.
I think everyone agrees that PvP battles would be MUCH better with no crit buffs. You'd actually have a chance in 3vs1 battles which is really all PvP is anyway.
I'm sick and tired of bugging MAs for crits just to be able to compete in PvP. This one fix would make a world of difference and would actually allow some title huggers to wander away from a close zone. Allow some casters to actually use more than one nano before fight is over. And introduce some strategy back into a part of the game that has is currently a 'who sees who first wins' debacle.
Fix it CZ or Cosmik and the playing ground will level off fairly quicky imo.
