I’m running 5 shamans atm endgame. It does fine, gear is slowly making things less arduous. I’ve cleared lbrs, scholo and strat live now (quest runs) and it’s been a lot of fun. I’ve ran as 4 enhanc and one resto since early levels and around brd designated one a tank enhanc who uses a 1h shield and rockbiter. It actually plays really well, simply have that dude earthshock when your others frost shock and with rockbiter he snags mobs pretty well. Building a caster set since this is running so smoothly and will probably convert to 4 ele on resto by the end of the week. As far as buying water goes, leveling I just bought the highest water for the resto and the 2nd highest for the enhanc. It worked well since they have smaller mana pools and kept costs down
