Enhancement to have the option to rock either DW or 2H - if they can do it for fury warriors (TG/SMT) and for frost DK's - why not shaman? You'd possibly have to have a 'strength is turned into agility on weapons' included so that there are more 2H weapons available. 2H would be a bit more RNG, Windfury would hit HARD again ^__^ (BRING BACK 2H TRIPLE WINDFURY CRITS OF DOOM! DOOOOOM!)
4th Spec - Earth Warden. 1H and Shield, uses rock biter and stuff - just like we did back in vanilla when a few abilities had tanking side effects (extra threat etc)
MW to increase the number of targets that CL hits. (I'd not really change the current AoE rotation, as I think its quite interesting even if it has a bit more ramp up time.)
Fulmination to Buff earthquake - so that during AoE you can throw down a harder hitting AoE and then spam your CL.
Ability for enhancement shamans to weild swords - could open some cool transmog options
I'd like to see another melee ability for enhancement (especially if given a 2H option - 1 to replace lava lash plus 1 more)
and to copy/add to minor glyph suggestions already made:
Glyph to make weapon imbues overwrite enchants.
Glyph to make overload procs more visible - change of colour or something.
Possibly a glyph to adjust the colour of lightning spells in general (like monks have)
Glyph to make windfury more visible, bigger and generally awesome.
