Not that it matters but if you check the country stats page you can find out were the action is going to be and go to that side from the beginning unless something else has changed?
At least as far as wining of the war, or preventing it.
One hour rule would be fine, instant side switching would kill the arena even more,, Not everyone goes to mid war or early war just to kill or get killed,,
so expert ( insert name here) knight kills novice bishop a few times,
,, novice bishop goes and fights rooks,
expert ( insert name here) decides he's not done killing the new guy and in the end runs him out of the arena all together,,, and this helps HTC how?
One hour isn't to much to ask,, run a supply trip or three and your hour has passed
