I'm posting the specs i use in most fights. Obviously i have pretty high aggro so if you feel like you're lacking in anyway feel free to have a look and we discuss it ingame if you like. In my opinion, 3 DT's with similar specs and similar gear should virtually be able to swap on combos, and definitely with an irritate thrown in. Particularly in T5, if we can get our DTs running similar specs, swapping aggro should be much easier.
Mitigation Spec - Sheng, Yak, Vizzy

All these specs have been refined pretty hard with the help of some of the best DTs ive ever met in the game, so im pretty confident in them. As always with some specs, there are some points that could go about anywhere with no big difference, but they are all designed for max aggro. Soul barrier is junk in most high tier fights, and Improved dread fury should almost always be run, even if theres 2 DTs in a group, just to pre-answer a couple questions. The point in Cov of Pest is there for fights like Arbanus and T3/5 when u may want to swap between increased mit and increased dps thru the fight.
