Gurtog:
Did as MM. With my ~180k HP it was very easy, but you may have trouble if you have a lot less. The only real "tactic" here is to FD and do as much damage as possible during Fel Rage. I did it with 1 pet, you may need to switch pets (again, if you have much less HP).

Mother:
Again MM. Very simple, but potentially also very deadly due to fall damage. The "hanging wall" we used on 70 to avoid it seems to not work, but disengage of course does.

Reliquary:
Did as MM. Grab as much stamina gear as you can, Prismatic Elixir highly recommended (though I did without). For me the fight lasted 29 minutes, during which the 2nd phase boss did around 7 million damage. The tactic for phase 2 is simple, use all tools you have to survive, dispel the shield, interrupt and of course heal yourself and pet. Phase 1, simply FD, wait until pet is almost dead, dismiss, resummon, repeat. Phase 3 is faceroll. Screenshot


Teron:
Did as BM with spirit beast (and does not seem to be possible without). He has a 10 min enrage timer. 9 minutes you spend lying in FD, 10th minute you do damage.
Since FD has 6 minute duration, you will need to let your pet die. If you do the logical thing - attempt to reset the boss like Jider did with Patchwerk, Teron will get stuck on 1 HP and refuse to die. Because of this, you cannot allow the boss to reset and you cannot allow him the 2-3 seconds he needs to start casting Shadow of Death on you. Therefore, you need to get up and shoot him just as he finishes your pet, resurrect the pet, and continue. It is possible that you will be able to reset without the bug I experienced. Doing so will make the boss much easier.
The actual hard part is making the enrage timer. With my ~375 gear, I had to use all consumables, 2 potions, and I still had around 1 second on my Shadow of Death when Teron was killed. Screenshot

Council:
With my level of gear, does not seem possible. The damage done by Priest+Rogue (not really avoidable) is more than I can heal, even with 201k HP. Perhaps in the next season someone will manage it.

Have fun soloing Black Temple.
