Howdy there! Like Watermist said, My thread about a skip for spine has been there for a good few months.
Unfortunately as seen, the potion did not help as the Spine of Deathwing encounter still took me 40 or so minutes to complete, including a few wipes. The issues is more to deal with the overwhelming amount of stuff happening on the screen at once with the threat of being thrown off the back. Its akin to overstimulation of the senses.
