Guys, this is probable gonna be a pretty noob question, but here goes. while in cat is there any action i can do to stop casters. Like on rogues you have kick and for the most part each class does to or a action equivalent. Or do we have anything like that in any form? Thanks in advance

Bear form has a bash once every 60 seconds, in catform you would have to rely on your high attack speed and raw dps to lessen the pain yeah your still going to get hit by spells with good dps and a few hps you should be able to power threw most of it, Remember you dont Have to stay in one form and alot of the time swiching is the BEST tactic you have in your arsenal pop out of whatever form and touch off a heal swich to bear to absorb some of that extra damage or bash...

Oh and im not sure if your a Tauren or not but you also have warstomp once every 2 min

the tidal charm is a common thing to use in pvp. ya have to camp for it and some people have posted horror stories about getting it but i got mine on the first try.

You can kinda lock up spellcasting for a few seconds.
If you're fighting a caster, I'd suggest opening the fight (assuming you're stealthed) with Pounce instead of Ravage.
That's a 3 second stun. (with Brutal Impact)
Then back away, go bear form, and Feral Charge.
Wait till you see them casting somethign else, then Bash.

Granted, you're not going to get much damage in there, so it's not going to really help you one on one, but if you're with someone else that can do damage, like in Battlegrounds, it's very useful.
And it's not Feral-only. Most resto druids went for Feral Charge, and probably picked up Brutal Impact along the way.
