Guild Wars 2

I was in this kill as well, would really like to get some kind of dev comment on this as its difficult to convince my raid go for attempts at the eternal title without knowing if this achievement is bugged or not.

Elementalists have a pretty good rotation underwater that does decent damage as follows:

fire 2->arcane wave->arcane brilliance->water 2->water 2 detonate->water 3->water 3 detonate->water 5->air 2->air auto until arcane wave and arcane brilliance comes off cooldown and then repeat the rotation

There’s enough blasts in this rotation to keep 12 stacks of might while water 2 and water 5 both do decent damage (water 5 being similar to pre-nerf fgs rush)
air 2 provides some vuln and air has the hardest hitting auto if all 3 hits connect.
