If you wanna noe which is better between a int bp or a normal bp, i would say a int bp cause it can tank better but just that dmg is lower. If you dun mind taking very long time to kill a rogue, you can try int bp tho XD... Cause go and tink about you vs a rogue which rogue normally minor healing themselves and i tink ur dmg cant out beat their mh. And you can use ur heal but rogue can cancel heal, so end up you will be losing. End of the day if you want to hit, make a rogue and play as melee XD. Priest is better to be support =).
P.S : this is just what i tink after playing few servers as a priest =.="
