That is good idea but in the same time when ever happen that to me i just go and lvl my champs up. There is always something to lvl up :)

just another good idea i was in a arnea fight that no one could win just ketped healing up lasted 15-20 mins before i soad f it and stoped it but i also lost 10 points tomy score my idea is to have and aout raw timer where it just stops the fight like at 5-10 mins in if no one has won and no one loseing any thing sup the arena token used to start the fight

That's right, I had a fight, and between the 2 champions no one could win, it just kept going. I close the whole game. Otherwise I would lose points if I ended the arena alone

I also support the idea of a draw with no winner and no loser. I shouldn't have to suffer a loss just because my opponent is a computer with nothing to do, while I have other things to do and can't wait endlessly for a match to end. I understand not everyone would want this, so maybe it's implemented as a "take a draw" button that appears after 5 (or 7 or 10) minutes of active battle. That way people can choose to keep going if they want to. 

Now thats wonderfull idea! I have couple of times match like that but i was stuborn and put on auto  and do my other things in real life and when i come back to check after 45 min the fight was still going on and on so yea i log off and lost match and tokens.
