Today I had to watch 10 minutes how the other team of 2 destroyed our citadel. They had more fun to kill me at the health stone instead of concentrating on the citadel.
I wanted a "surrender" option so bad! Like saying "GG i give up. You won. Let's start another game".
It is true that a couple of lucky or clever kills or unlucky/stupid deaths early in the game can pretty much decide the outcome, so if you've alreay lost, why stay?
I've encountered both of these series of events.
In my own thread, I suggested that there is nothing for you to do in this game if you are on the loosing side. I think this is because the most common way to loose in this game is to be pushed into a corner, and then you're stuck (for example, in a FPS, you respawn at a different location).
I'll reiterate the suggestions I posted in that thread:
1) Make the game fun for the loosing side as well... (reduce cornering and improve Pantheon DG match-ups to make them fair)
2) Improve the social aspect of the game... (call-for-help-shortcuts which are visible on the map, permanent chat display, etc)
3) Improve the AI for people who still quit... (the AI stands still too much, I think, and should react to those call-for-help-shortcuts)
