UWSC armor/usage

Disclaimer: I did a lot of UWSC as bonder with pugs, friends and so on, then this happens:

So i was in this team as bonder, and i had all enchants up, and i was keeping up with energy degen while tank was pulling mobs at the start and it was fine, but when the lab tank paused to cast i was hit by huge energy degenen, far more then i gained back from ER and i tried to counteract by frenetically (more than usual for people who don't understand) spamming burning but to no use, then you know the rest.

Now the question is can lab tank have wrong gear or not using skills right and then far more hits are 5%+ and if so any suggestion on how to prevent that, as I'm sure it was not my fault?

What exactly is a lab tank? if you describe it more acurately more people would be able to help.

labyrinth tank

How many mobs did he had on him?

Learn to ER like a man.

Some lab tanks takes Mental Block some not. Even if it's 1 skill it's a huge difference for you. Since you lose energy from every single hit he takes instead of taking 1 hit here and 1 hit there. Can't really think anything else which would matter much on your job as E/Mo.

Shroud of Distress of course but it should not be too hard to maintain for LT.... Just remember Balthazar spirit on yourself too so you gain even some regen from the hits he takes.

use corn or eggs at the start and at dhuum and get better

I guess you didn't read the disclaimer, and getting better so others can go by being worse is not a good option.
