Shamanistic rage is now trained at 65.
Why? Give resto ele and enh survivability in stun that is much much needed. Make shamanistic rage also regen mana on spell cast to help resto with mana issues. *Also makes the shaman immune to abilities that slow casting speed. Maybe small nerf to ele clear casting to balance.
Replace shamanistic rage with a small aoe ability. Stormfury or Earthstrike to continue synergy with nature dmg on stormstrike. Make it a 10-15s CD but enough dmg to help with burst.
Why? Enh shaman have marginal aoe and need help with burst on plate. This change would help with both a little and would add synergy to the class and make it feel more unique.
Cosmetic change: remove the glowing feet holy animation from chain heal. It looks like rez and makes us look like we're casting a holy spell. Since this spell is the "niche" for resto shaman it should be a little more tasteful.
Give grounding totem 3 charges. Grounding used to be good but now other classes have cloak of shadows, antimagic shield, etc etc. It should be a viable strategy for a target to have to kill our totem instead of just hitting ice lance. This will help against arcane mages and destro locks. If the totem is targeted then it dies right away, but can absorb 3 spells before it dies.
Lower CD of grounding totem by a few seconds.
These changes are not groundbreaking and would make as an actual class again.
