1) Successful spell casts get 50% runes refunded: My guess is this will Oops every time.
2) War declaration requires 2 different provinces to start it: My guess is no one will be able to enter a war initially
3) War win reward not granted if out of range to start - Will either not grant a bonus to an in range war or will still grant a bonus to an out of range war, hard to tell.
4) War room wont default to at war kd at start
5) TOG reduction - Will be reduced but not by 33%.
6) BE will still matter on guilds as far as duration goes
