I don't see anything in those notes addressing the fact that elemental shaman hit like wet noodles even though they're hard casters. The only other pvp hard caster is a Shadow Priest, yet they hit like trucks. Mage and warlock specs allow instants that hit harder than elemental blast. The only way to be on par with damage is to get extremely lucky with RNG mastery procs. This while fire mages instant pyro for 120k.
