When in this raid, there's a few more things to add for you to know. It's not like I know it all, but here goes!

1. Bezerkers can knock you back a long ways, and they also have an AoE fear. One tank will not be able to hold aggro on him during an entire fight, so watch out. Other tanks , knowing that one tank won't be able to hold aggro, will probably be best off taunting whenever they can. Hell, even a secondary tank may know to stay a way until the first wave of fear hits, then going in to intercept aggro before the bezerker kills Baeloc. When choosing to fight one, you must be sure other patrols and stationary groups of npcs are not nearbye. 

2. Blooddrinkers have a short range AoE life drain. They are to be killed last and away from the raid using range attacks while the main tank holds them. If too many players are near, the blooddrinker will drain the life from all those players simultaneously, prolonging his life, and irritating us. 

3. Priests, similar to Bezerkers, have to be fought in areas where you are certain won't risk training wild aggro due to someone getting feared into a nearbye patrol or stationary group.  Shamans drop tremor totems to nullify fear effects when these npcs are in camp.

4.  Batriders will emote a warning that signifies they're about to expode. This takes place around 40 percent life. Pre-emptively foresee this explosion and begin leaving melee range of a bat rider at 50 percent. Range damage will take care of the rest. Tanks must hold bat riders at a safe distance from the main raid, as well as away from other bat riders being tanked. 

5. When tanking snakes, turn them away from the raid. This neutralizes the traits of the yellow snakes, but it's just a nice habit
