I dont use addons at all for heals- personal preference, Im not going to rant against them- I dont use them, thats that. For me I just use my mouse to click on the person in the party and then hit the numbers that go along with the heal I want. Anti/Exor/etc etc are normally on the keys right above 1-2-3-4 so I know where they are. Fountain- just click on someone in the party I want to heal and hit 4. Then click back to the tank and continue on

Ive never used addons- and probably would just get frustrated by them (who knows?)- but thats just me. Im used to doing it the hard way ^_^
