Well next run try this and let me know if anyone goes wrong.
Mark North side A, Mark southside B. Tell them you will Cover B.
Grab the Hardmind that spawns after the initial first 2 mobs will die with Unmend, if your party decides to nuke this off the bad do a power slash combo, otherwise do a delirium combo. No mp issue.
The next Hard whatever will spawn, Grab this as well. Do a PS combo finish up with delirium combos and/or throw in a DA SE combo. If you went reckless just drop sole survivor on something as its dying.
When the A's side mobs die and this hard mind the middle mobs will spawn. You can hit Unleash to grab many of them, Plunge the other, and Unmend another if necessary. Hit unleash again, if you have the aggro of 3 or so. Mark the boomtype as [1] or at least explain that to the team beforehand if you dont want to or have the speed to do so without messing up your snap aggro. With DPS focusing boomtypes and already establishing some aoe aggro with unleash you can do a PS combo and then go back into Delirium/SE combos. Make sure to have planted Salted Earth. While salted does not have an enmity bonus, doing damage in general generates Enmity and Salted is 525 potency AoE.
If you're losing aggro at this point it should really only be because the tank at A (who will also come into the middle generally) has also attempted to snap aggro, this isn't a problem. As they die grab the Spider on B's side (South). There should be no problem with Mana here given even if you went over zealous holding aggro here isn't a problem and you'll of course have plenty of time for Delirium/Soul eater and DA soul eater combos. Again keep mind to use Sole Survivor when applicable. The Jagd doll + Gobs will spawn. You can unleash all 3 off the bat. Then Power slash combo the Doll and then go into your (DA) Soul eater/Delirium combos. Do a quick tab cycle through the three of them ocassionally to make sure healer/DPS aren't trying to pull the gobs aggro while you deal with the doll, if so just drop another unleash and carry on. You don't actually need Abyssal drain to hold aggro in this fight (to be honest I find the ability somewhat booty) but it is certainly available at times especially if you're got a handful of mobs on you.
If I recall at this point after the dolls dead it's middle mobs again. So Grab them as you did before.
Then go to your side when they're dying to pick up the Boomtype + adds. Have the A tank grab spider + Doll given Spider deals shit damage.
Get your crap killed, run some syphon combos on A's spider again... then go up and grab the double dolls in the South western corner. Once those are dead you've basically won the fight so w/e. You can mark which Jag'd you want dead first if you feel the need
Again keep salted earth up on while aoe tanking and you'll pretty much be fine. This operation goes in general for any tank (Over power/steel cyclone/Flash/Circle of Scorn) for handling A2. If you're on A (north) it's just picking up whatever is on your side and the Doll that pops up in the eastern side.
If anything I'm saying seems "Well Im doing that and it's not working" let me know but it should be fairly straight forward.
Unmend a ranged mob. Only need 1 power slash combo then you can SE/DE/DA + SE. If you need more then that you'll know just take a glance at the aggro bar in the party list. Make sure everyone knows to kill Boomtype and Dolls on sight and you won't really put in any effort in the aggro of the lesser mobs.
If you basically follow this
1. Mark North A, Mark South B. Tell the other tank which side you are tanking. Tell DPS to kill Boomtypes and Dolls on sight (tell them to prioritize Boomtypes first if you're doing B, for when that Eastern Doll spawns) and you'll succeed without problem. Can farm this on Duty finder without a hitch just communicate those simple things.
