So I've seen something like this before once and the thread vanished so something positive for the forums

Fractal: the second boss groan attack can be stopped by releasing the monsters in the tube, making your healers job a bit easier and giving them more time to dps now depending on your groups overall dmg you should only see the field wide swing twice which gives you an extra two tubes, I know this may seem like something a lot should know but I haven't seen anyone do it yet besides myself

Thordan: during the electric attack if you stand in the small circle surrounding the crystals you will negate the attack a lot of ppl don't know that cause the trial is so easy and quick

Bis ex: Caster dps if you stand right next to the DKs during the snakes phase you will not have to move out of the way of those annoying twisters, I notice this all the time caster dps drops cause they have to constantly move around

Well I only really had a couple but please feel free to leave advice that someone new may not know about, or correct me if I sound like an idiot and you have a better way!!
