If you haven't noticed, Grid has received some great updates with Cataclysm. Clique has been updated many times but Grid has just recently been given a face-lift (well, the options have). The interface is much easier to understand and much more intuitive. I encourage you to take a look if you were puzzled by the interface in the past. Personally, I like the mass amount of options and wouldn't trade it for Healbot any day of the week. The new interface really makes those options more available and easy to understand. Go try it out, NOW!
Grid and Clique: a healer's dream.
