I actually figured a way to assure that the MT (warr) won t be killed by being out of LoS of healers when he is feared.
My thought is simple. Assign as hotkeys to your stances Mouse wheel up (battle stance), mouse wheel middle (defensive) and mouse wheel down (bersesker). This trick helps a lot generally throughout the lvling-pvp procedure.
OK. On the fight. MT (like everyone) has to have DBM addon so he can see when the next fear is going to pop. When DBM 's "Next fear" timer reaches 0 (or a few msec before it), mouse wheel down (bersesker stance, yes!) and activate Bersesker Rage (Immunity to fear, sap and incapacitate effects) and then quickly switch back to defensive (middle mouse)! You won t have to worry about the sudden reduction of rage cause each hit from nightbane gives you lots of rage, plus Bersesker Rage doesn t need rage to be activated, PLUS it only has a 30 sec cd so you can do the same procedure on each fear!
So, in a few words, it should be something like this:
Fear warning bar reaches 0, mouse wheel down, bersesker rage, mouse middle button.
That way you don t need a priest for fear ward, nor a shaman's tremor totem near you. I hope this helped!
