Also I don't think that really counts as a gauntlet, gauntlets are things where you have to keep running to get to the end and if you stop you'll get swarmed, that is just regular trash pulls with a bit of wind on some platforms.
The trash after durumu, that's an example of a gauntlet
Eh, happens. The boss LFR is most likely to wipe on I think is Dark Animus, then there is a few like Jin rok that if you wipe then just leave because that group is in greens! the rest if you wipe or not is just hit and miss in LFR, you usually won't but stuff happens xD

And Ely when you get up to durumu, his eye beam will connect from him to where you entered his room, if you touch it you insta die. On one side of the eye beam the floor will be electric, go stand there because the rest of the floor will become bad stuff. Then the eye beam will slowly move towards you so you have to run through the bad stuff in a clear path maze that opens up.
If you can get to the electric floor and avoid getting hit by the eye beam you'll probably live even if you spend half your time in the maze in bad stuff, but don't screw up! Half the group usually die to that xD
