When I was learning to be a feral druid I had the hardest time knowing what sort of stats were good. Was 30% dodge enough? 35%? How much armor do I need? Etc. So I thought I'd share where I am stats-wise now. I've been playing the game a lot since Wrath came out and have most of the level 200 gear I want from heroics and Naxx/10 and a few level 213 pieces from the 25 mans. I think I'm now as well geared as I need to be until the Ulduar raid comes out, although of course I can always improve.
All stats below are unbuffed.
Cat form, cat gearHit points: 20467
Attack power: 6084
Crit chance: 43.16%
Hit rating: 184
Expertise: 27 (dodge capped)
Cat stats vary wildly during a fight. With my Darkmoon Card, Savage Roar, and raid buffs I'm at about 13,000 attack power and 50% crit.
Bear form, bear gearHit points: 32467
Armor: 31271 (67.2%)
Dodge: 38.85%
Hit Rating: 71
Expertise: 30
Attack power: 4329
Crit chance: 35.24%
Hit points go up to 40-44k with raid buffs, and dodge varies up as much as 50%. The armor nerf's going to hurt me, I'll probably swap Defender's Code for Essence of Gossamer and trade a couple thousand armor for 1600 hit points.
Bear form, cat gearHit points: 27087
Armor: 23319 (60.5%)
Dodge: 39.14%
Hit Rating: 184
Expertise: 27
Attack Power: 4717
Crit chance: 43.16%
The hit points are a bit lower than I'd like, but I'm perfectly viable tanking most things in the cat suit.
