I can't believe no one had brought this up yet, so I must have just missed it . . .
Without changing when ENY kicks in, this setup is unworkable. 85 to 76 to 28 in the late war 2 arena, no eny limit. In fact, an ENY limit is IMPOSSIBLE unless the arena is completely full.
This in no way "limits hording by spreading them out" as some have claimed. This makes hording far worse. Change when ENY kicks in and/or make it a 2 sided war, or else these arenas are just too small to self-balance.
Also, 2 arenas are near their limit, and 2 less than 25%. If the server capacity is now 900 (assumed since 250+250+200+200=900), is there any way to make the capacity "float" to arenas that are almost full from those that have plenty of room?
