Until recently I've thought that pretty much everyone just uses mouseover macros or some form of mouseclick like clique/vuhdo/healbot to heal, but most people I speak to and a lot of the pov vids I watch don't use them or don't even know what they are and instead click to target and then mash the spell.
Now I'm a strong believer that mouseovers are best, but even the likes of Jhazrun and Xabok do the whole targeting first thing which leads me to doubt there's a big difference between the two styles. Specifically to paladins however, I feel it's just overall better since we use mostly targeted heals.
What do you use and why?
