Kritias in August

Kritias is pretty disappointing yeah, the quest line is short and the area is pretty annoying to navigate (especially during invasions, you can't even sit on a chair while one is going on -_-). I know some people train there though at higher levels, apparently when an invasion happens, it becomes a good training area?

Mhm.
It's pretty godly, for the most part.
I don't know how it is post U&I though, but during RED it was pretty popular and for a good reason.
(Chances are that post U&I, it's even better)
