Black Ice Tooltip
Black Ice says it affects "spells" but I believe the way it is set up is just to improve Frost and Shadow damage. I'm not sure if anyone has tested that or not. Changing that tooltip could have a big effect on Frost and Unholy.
The Bloodworms should heal you for 150% of the damage they do. If they hit for 30, they should heal you for 45. There were some bugs with the calculation until recently.
We turned the aura icons off. Once you get the talent, that aura will be up all the time so we thought it was annoying to have the icon always there reminding you. Most passive talents aren't shown as icons. It shows up for the other players in your group, however, to remind them.
As far as the previous poster who likes the Feral as the tank / dps hybrid, I don't think anything we're doing will really hurt that. You may be 5-10 talent points behind a tank-focused Feral or a dps-focused Feral but if you liked OTing the bear boss in ZA and then dps'ing on the eagle boss, you should still be great at doing that. The difference is the bear who does spend those talents on threat, mitigation and oh snap abilities instead of +Shred can actually be a raid's primary main tank.
Arms / Overpower
I can't recall if I mentioned this, but one thing that comes up a lot is letting Arms get better use out of Overpower in PvE. No promises, but I wouldn't at all be surprised to see something like this.
