Endgame Content?

Hey guys,

I know this is tech forum, but everybody seems to be here.

I am level 50, and I have had huge issues with servers also getting up here.

Just wondering what kind of endgame content is there right NOW at 50 (i finishes story).

I know 2.1 crystal tower, but how many dungs are der now?

Not 50 myself but every dungeon should have a hard mode, and this could probably be answered better in a different forum.
