Thats interesting! That was actually the build I wanted to go when I first made my Shaman on here... but I really dislike PvE and had to settle for enhance armour through PvP grind. Can you link me your talents? For druids though, it feels like they outlast me but since you are resto and have so much mana I can see how you find it easy. I've tried out so many specs, my spec reset cost is 50g now so I switching is too much of an investment for me, even if you said it wouldn't take long to get some gear as healer sham... no one takes enhance shamans T_T. As for warriors, I have a hard time dead-zoning them I can't tell if its because of Vanilla distance ranges being iffy, the server, or just my skill.
Also, maybe you can check out this spec I was thinking of going: http://db.vanillagaming.org/?talent#hAbzEcGqoxibz
It opens up being able to use CL and LB, while giving me the on demand crit and 9% crit damage, I would be using rockbiter instead of windfury to get good crits and dps off. This would also make warriors not able to charge from the 36 range rank 1 LB, and can outrange mages CS incase they kite me away too much. I would start off ranged, then switch to an enhance style play, and if I get kited I would switch back ranged.
