Main thing is doing the same thing on 1 key, and doing that on each toon. So maybe 2-5 will be your DPS keys and 6-0 your heal keys. All kinds of ways to do it. My very basic setup for shamen is 2-LB 3-earth shock 4-fire shock and 6-LHW I use a key for follow And build assist into each attack key. Using focus for now sets up in 15 minutes, maybe 45 minutes for 10 toons
