You are heading into wrong direction. Self-buffing is not an option in pvp system. If you do it to temps (mb and other buffs)/priests (alm buff) then lowbies are screwed cuz they won't be able to do anything in dungeons - I mean grinding. Also to be able to pvp and be on par you will need to spend thousand of dollars to get rp and get boss drops for +12 or +18 at least, now top temps still hit hard and to bo on par with them you need boss drops, without it templar won't be able to do anything at all... 1 step forward - 2 steps backward... This is going to be really sad if self-buffs will be made, wrong direction, just wrong.
Taking heroic power back just for defense was enough to nerf entire classes on rohan including temps as well.
