Since it is still fairly early in the expansion there is a lot of stuff going on which we have no clue about because it was not tested on beta (trash in raids for example) or something that was overlooked.
So I figure we can add things we note while playing here that may help each other out. (feel free to include anything that you may think is common knowledge, some people may not have thought about it if they are still in lolfaceroll wrath mode)
My two so this post has a contribution:
1.Heroic Throne of tides- the right side gigoblin pulls were they throw the poison spears, have any rogues sap.. then run in with ams up while your other cc follow up with their ccs as ams will absorb all the poison spears they throw at you, turning a rather annoying pull into a super easy one.
2. Halfus Wyrmbreaker (bastion of twilight) The drakes hit extremely slow and as such really hurt your 5sec rule of bs goodness, let one of your other tanks tank them and you tank halfus, he hits rather quickly and is much easier for you to mitigate then the drakes. (I noticed 3/4 mill dmg less taken over the fight duration by switching and the tank i switched with only gained about 150k more)
