When I don't play with a healer I just toss a chain heal macro into my rotation, with all 4 spec'd into echo for pretty big heals.
I hope the CL changes make it to 5.2 (Jumps do 100% dmg instead of reduce dmg per jump), then I'll prob include that in my pvp rotation for Maelstrom stacks.
I've been debating specing into Instant Cast Elemental Blast x4.... to try and land 2 insta gibs out of the gate. Wolves/Eles/Ascendance out of the gate on Target1, then switch to target 2 and get them down to like 60-70% and 4x Instant EB.
