About the time limit issue. I know it is not the right place but since it has become a topic here I might aswell contribute.
We are a combination of players who wants longer battles, shorter battles and the possibility to end game if the players agree. This we cannot change. All of us will have more time every now and then and other days just a short gaming session before training, bed or whatever.
One solution could be to offer different kind of battles for the player to choose from, like
Play time limited game (i.e. 15 min, 20, 30 or whatever) Play non time limited game
I am certain both options would be used and I am almost certain all users would like to be able to choose based on their RL schedule. What I like about games like WOT is the possibility to plan ahead and quit when it suits you. The other day I tought a fast battle in Naval Action would be an options. It was not and I almost did not make a meeting at work...that was not cool. Note to self "do not play NA before work".
