2.1

Here is what I know about MW 2.1:

CONFIRMED/LIKELY CHANGES:
-Officers will be able to attack GVE castles.
-At least two new heroes.
-Bugfixes.

POSSIBLE CHANGES:
-A guild can attack multiple GVE castles.
-Changes to the way hero stats work.
-New gear and,
-a new crystal sale to get this new gear.

RUMORED CHANGES (some can be unlikely):
-A new morale skill.
-A new special stage.

I will add to this as we get closer to 2.1.
