As for being heavy. I think if you look it over AceHeal is not very big at all. That was one of my prmary goals to trim things down. Now if you just plain don't like click healing and prefer using the action bars then yes AceHeal isn't for your. If you don't like the spell rank selection etc but like the idea of click casting then you can bind spells by name and name/rank to the mouse buttons which will then only cast the exact spell you set it to cast, ie just like the action buttons. Basicly it allows you to move the healing buttons off the action bars and put them on your mouse for faster healing also freeing up your action bars for other things.
