Arena/Fleet Battle Timeout solution

Well there are 2 shoes.  The other shoe is your opponent who is glad you timed out.

I don't really have an issue with your proposal for arenas, it's just a climbing environment after all.  I think though, with more experience and a better portfolio of teams, this will become less of an issue for you.

However, for GAC part of the strategy is putting teams on defence to timeout your opponent.  If your suggestion was put in Grand Arena too, that massively affects the playing environment.

After some thought, your idea couldn't really be used for GAC I guess, as there are no draws.  Also, a possible drawback is that players use Arenas as a 'sandbox' mode.  Testing teams against certain combinations.  Having draws gives you the option to practise vs the same team again and again.
