Yeah I joined on patch 3.2, so I only had to deal with original CU for a couple of patches before its buff.
But gosh I miss stances in dungeons too. I loved swapping to Nocturnal after a pull, swiftcasting Stoneskin, applying Aspected Benefic, and then swapping back to Diurnal for the pull proper. All while keeping up the cards, it was a fun time for dungeon AST.
