its basically a personal choice, but i chose the healing spell because what i've seen is that it will grow with you as you level up. example being that at lvl 30 it heals for, lets say 450hp, and at lvl 31 will heal for 500hp. not exact on the numbers, but you get the idea. This thread helped me out alot in making the choice http://eqiiforums.station.sony.com/eq2/board/message?board.id=20&message.id=1285
