I actually like the earlier surrender since getting a leaver isn't all that uncommon... The only time it bovers me is when you're on the dominating team and you just maxed out your meja's. :P
New champ every 2 weeks is annoying though. Makes it less special, and by the time the craze for one champion has died down, there is another one up. I hate facing the same character over and over and over.... They should focus their time on patches and release a new champ once a month. /2cents
But I still love this game with a fiery passion that burns through my soul.
