It's happened to me in my last 6 or so dungeons, both on my rogue and cleric, both have about 9.5k gs but I can't raise it further as I am kicked before I can loot true T2 gear rather than my of the drake stuff, with the cleric I was always the only cleric, you'd think they wouldn't want to deny a healer gear but…
I have no idea if it pleases me or not that I went for an 8.3k rating dungeon, which I had been avoiding due to confidence being low, and found it so much easier
