I recall a few blue posts before (or just as) the 5.4 PTR begun, stating that Blizz wants to speed up Enha's AoE ramp and that they also want to change Elementa's Earthquake (i think Magma totem as well) so that they are actually useful for DPSing.
However we are quite deep in the 5.4 PTR now and so far there are no hints or Blizzard posts about Elem/Enha AoE changes - so i am kinda worried they forgot or canceled it all without letting us know.
Does anyone have any new info or blizz quotes about the supposedly incoming changes to Shammy AoE spells/mechanics?
EDIT: A really awesome suggestion i read about is making Fulmination boost Earthquake's damage (and perhaps reduce it's cast time). That way Elem could spam Chain Lighting until max Fulmination, then cast EQ and resume CL until the next EQ+Fulmination is ready.
