Honestly, I really enjoyed Castletown. I'd in fact, make it even more chaotic with things happening all the time, not just intervals. What I don't like about this map is how it looks a bit 'off' with how linear the crystal push design is.

All and all, CC is good, but going through a whole expansion just with CC (because let's face it, Frontlines are horrible as they are) gets old really fast. I really hope that 7.0 is going to introduce more modes with light parties instead, or at the very least different layouts for CC.
