So far what I've noticed during the 2 hrs I spent running a few heroics:
1. Mana is not an issue at all. I had no bread/water and rarely did I have to stand around and wait for my mana to regen. In fact I don't think I went below 50% in combat at all. Watershield + mana totems stacking is OP I guess. Maybe its the 1sec regen ticks now, I dunno.
2. Was wondering without Lava Burst, is flame shock worth it now with the increased DOT? Maybe I'll put some points into Lava Flows for the +15 yards and test it out, the +15 should bring it up to 39 yards? LB/Chain/Flame shock combo 35+ yards out. That should work.
3. With 5x shamans elemental oath is up just about 100% of the time. If I want it up before a pull I just lesser healing wave a target with all 5 and it'll be up.
4. Thunderstorm is nice
5. I need some glyphs.
