We are not getting content more difficult than Twintania.

[Tribunus]

Yoshi P predicted 100 people would beat Twintania before patch 2.1 but only one or two groups managed to get the legit kill before the nerf.

Thats because we are missing an entire tier of gear progression and most groups are stuck behind a gear wall. They should have imo just given us this uber hard crystal tower they went on about and adjusted accordingly.
