The latest Cheaton, i mean addon (not like it gives you god mode or 50k dps) that might be worth looking into for our raids is AVR (drawing addon front end) AVRE (boss encounter mod of it).
AVR basically allows for drawing and shapes to be put into the game and AVRE draws those shapes in a relevant to ICC encounters (mostly).
such examples for us would be a circle drawn around the player with a spore in festergut that allows you to see if you are close enough to be hit by the exploding spore. this is also helpful to see easier which side you have to run to on 25 man where there are 3 spores instead of just 2. another example is on rotface when the big ooze does unstable ooze explosion, all the area's on the
ground that will be hit have a circle drawn so you can see to not stand there rather then just "run away!" and hope your good.
last couple weeks i've heard a lot of talk about it in and out of the game, so i used it and was quite impressed with what it did in icc25. could be something quite useful if we want to progress further with downing putricide or blood princes.
