Well, since I made this post, I've started a druid team.
All I can say is, it's absolutely nuts!

So far, it's a full Feral team. The 4 dps have a regrowth/rejuv macro that targets the bear. The rest are cats. And the damage is off the walls, super fast, super strong.
Especially if they're behind the target, an equal level elite will lose over half of it's health in 1 round of Shreds. The HoTs last through the duration of most fights. I'd imagine that Mangles will be even better.
Bear gets AoE with Swipe at low lvls.
It's great. Zero complaints really.

I got my Shams+pal team to 66. Went back to Ramps, but couldn't get past last boss. Even with grounding totems. The orc that drops off the dragon could 3-4 shot my pally. My pally is full outlands geared.
However I can drop a player in pvp very quickly. Even 80 only take a few rounds of lightning bolts. And x5 purges (x5x2 technically since they remove 2 things), will strip anything down to the bare metal (or cloth lol).

It's crazy how difficult TBC is for me, but WOTLK I blew through all equal level content. Even with an x5 ret group just taunt spamming really.
