Just wanted to share a bit of my experience and exitment about the resto spec...
I'm and old school BC player I've started raiding with my resto in Kharazan and have cleaned everything till cataclysm, where I've left the pve world and started PVPing with my DK.
I've just re-joined my old raiding guild this week and with 384 ilevel gear
I'm here to talk about TC wich I was very reluctant to take as never in my shaman life would I ever consider to cast a lightning bolt, I found while leveling and gearing (without TC) that my shammy was quite weak in mana-regen I was spending a lot of time waiting for my mana bar to fill up
After spending a lot of time in the forum I decieded to take a shot at TC with a 7/2/32 spec reforging all to Mastey/crit while maintaining 1900 spirit as for haste it is just over 10% (I've got 2 haste procs which i don't like but ok ...)
Damn how powerfull am I now, I've never been more happy with the shaman spec ever, yesterday was my first DS HC and we cleaned the 4 first boss with 9 player, I was undergeared and managed to 2 heal everything without any worry at all, I know there is a huge buff and but honnestly it was really too easy and I know that I could not have done this without having TC 2/2.
Mastery is f* amazing I'm just so happy to see someone under 30% and crit him for 90K+, TC is brilliant for gameplay this adds a lot of dimension to the fights, as regen is now an active thing, I can spend my stat in other stats rather than stacking this boring spritit.
