djc, Tauren is good for war stomp to give you some time in case you get adds or need to heal. 5% max health too, but that is probably unnoticeable until later than I've gotten. Troll could be very good for dungeons with beasts, I would think (looking at you WC).
Dr. Doom, Mizu: that's super depressing, although makes me feel less bad about having threat troubles against lots of mobs. I've definitely been able to hold and even pull threat with a single earth shock, but I guess that's because it is a burst of damage. I'll run a test and report also next time i log in. Tanking on a Shaman is the only reason I want to play vanilla. Are there other servers where these abilities aren't bugged?
I started over, trying a resto ancestral healing route. Going to stack agility for flurry and intellect for AH, spec will be
http://db.vanillagaming.org/?talent#hZVV00vxzZVf0x0xo to start so I can cast heals while tanking early on (which may help with aoe threat), plus the extra crit to heals for AH and chain lightning aoe threat, an instant cast CD, and reinc as a tanking cd (or a res and heal the crap out of next highest threat cd to save a wipe). last 5 points can go a lot of places.
I may also try
http://db.vanillagaming.org/?talent#hE0zxcZVV00txzZVf, though I lose the crit and some flurry.
I tanked RFC with a fast dagger, went pretty smoothly, 1 wipe, 3 deaths, I was level 15. Not enough points to really try out this build yet, but I'll update any way.
