Just a simple idea. Seeing how BT only procs from killing another player, it should cost, imo, favor instead of money.

Side note: All I do is PvP, side of dailys, and yea, BT is making myself, and other PvP only toons a broke sob after long grind sessions.

Would love to see it cost PvP currency seeing how it is a PvP only buff!

Thanks!
