Monday night, so everyone in guild was doing a few Mythic Keystones to round out tomorrows Vault. I healed a Mists of Tirna Scithes +4, then dps'd a Halls of Atonement +6. Finally I tanked a Plaguefall +7.
Or perhaps "attempted" to tank Plaguefall would be a better description of that run. The first two groups were timed, but that Plaguefall had 40+ deaths. Part of it was that it was unfamiliar to some people in the group, part was my noob tanking, and part was that it was Plaguefall. Quaking and Sanguine made it even harder, as there's not a lot of space and many mechanics encourage you to stay close.
Another problem was that I had forgotten I had got [Dreamer's Mending] last week some time, and had decided to try it in my tank set. Our most experienced guild tank had warned me against it, but it was an item level upgrade, and I thought it could be helpful.
He was right, and I was completely wrong.
All through the first half of the dungeon I kept wondering why I was getting stunned. Was this some special tank mechanic I never heard about? I realized what was causing it at the second boss, but you can't change gear in a Mythic Keystone. So we just struggled through it.
I vendored the trinket the moment I left the dungeon.
