well You want to swap SS and LL in places (giving LL a cd and make SS spamable) stormbringer would still improve SS dmg and make it free, now go to WW monk and try it, its exactly the same mechanic, you have tiger palm (resource builder) that make free blackout kick (weak spender) and raising sun kick(strong spender) have 9 sec cd, i dont find it that good personally but thats just my feeling.
tbh a lot of changes ppls sugest for shaman (tank post couple weeks ago for instance, is copy paste of brewmaster skills without it mastery) are just rip off from different specs, just with different look and some minor changes.
ATM shaman is more flashy warrior, your rework would change it into a more flashy WW monk with MS instead of chi points and mana instead of energy, and i read a day or two ago someone sugesting going DK way with fire, air and so on runes
For me it would be grate if they get back to CD based gamplay we had 2-3 expansions ago, good burst, allways something to press and look for
Just keep healing surge on current lvl, keep sunder in current form and AS as deffensive cd on top of that and we are golden.
Making a lot of simillar classes with different animations is not best game design imo... if i want to play some class i can pick it and play it there is no need to reworking us into something else that we have alredy in game.
Not to many ppls are plaing everything, i asume, so you may not even know that we have sugested playstyles alredy in game
