Hello,
Do you miss cata dungeons? They had some story (ds dungeons) they had some difficulty level (e.g. Dragha Shadowburner - some ppl just leave it and go to next boss). Epic 3 dungeons from ICC... Chellenge Mode is fun, but cant replace hc(real hc) dungeons. Scenarios? Pff premade only and now its one shoot. I hope blizz will bring it back in 6.x .
