Why aren't shaman receiving any help???

Check the sk-gaming.com rankings. Shamans are the worst healer in every single bracket by a lot. Every game with a druid is a huge uphill battle. Most games end up with the druid being at 80%+ mana while i'm around 5% mana because druid heals and mana return are so broken now. Mana tide is the biggest joke in the game when you compare it to a baseline skill like innervate that provides 3.5x the same mana return. Shamans have horrible survivability, horrible mana efficiency and horrible mana return. Shaman are so reliant on water shield to return mana by getting hit, yet you HAVE to wear earth shield when you are getting targeted to survive. That doesn't make much sense Blizzard...
