I love Quartz, its truly very helpful, for any caster really (will up your dps 5-10percent in raids if you use /stopcast spells) , even a few things nice for my rogue on it. Totemtimers is the best addon for all shaman for managing your shields, weapon buff, and totems. Currently using ora2, Deadly Boss Mods (has nice pvp bg timers too), omen for my raiding needs. I really like OmniCC for global cool downs, changes them to numbers from the blizzard default clock like thing. Auctioneer Advanced is really nice for making extra money on your sales. Gatherer is a must for herblists and miners. I also love MobInfo2 for farming, keeps track of all your kill's drops/dps/hps. The best dps/stats meter out there is SWStats the newest version is very nice. I breaks down your damage by ability , for example i know mutilate is 24 percent of ghosa's dmg during a normal session. Currently using Healbot, its amazing you just left/right click to heal people in bgs/raids/arena, don't even have to target them. It shows whom in range needs a heal/cured its amazing. Also using Bartender3 for keeping my bars small and compact as I keep only 4-6 things bound to the key board i tend to mouse click alot while raiding/farming (i tend to bind everything i can when pvping) (1-5 z,c,r,f,g,h) Thats my 2cents worth
