Can anyone tell me what to do like in dueling when im fighting a warrior what should i hit him with and stuff like that

try to get the opener with pounce, mangle, rake, rip.
Then switch to bear and mangle, lacerate him down.
If low on health bash, cyclone, heal. Back to bear.
Kill him.

A warri has high armor so bleed him down.

Make sure to faerie fire the warrior too - that adds a lot of damage.

If you can, the easiest way to deal with a warrior is entangling roots. Then walk away and mock him.

Well, the most important thing is: Never get hit out of bear form!
I mean... Never
And yes, not even occasionally.

I don't necessarily agree with that, I don't mind getting hit a couple times initially. I like to get 4 combo points and rip, then go bear. If he gets a couple shots in during that time, no biggie.
