I kinda like a few addons. I don't think I use a lot, but the ones I use, I love. Smartbuff. I admit, I didn't use it for a long time, but now, I don't think I would like to be without it. In a zone with water, turn on water breathing type of spell, push button, bam, 5 people can now not drown. When you are done with the zone, one click to turn off buff on the buffing char, and bam, no useless buff anymore. No wondering if buffs get out of wack, it notices when someone in your party doesn't have the buff (one char dies, gets dispelled, etc).
