I've only played the beta but I won 95% of the matches, and the thing is I've noticed a lot of people are that sometimes some will run away and then attack people that are already fighting. This is a major annoyance because when you have to chase people, you're not getting AP while the other people fighting are.
Eventually when times like that happens, I just cave in and attack the two people who are already fighting if the other person won't fight me one on one and feels he needs to attack the other people instead. The thing about this is that it could become personal to the players you attack and they would possibly gang up on you. Who knows.
As much fun as four player is, most of my play time will see 2v2 or 1v1.
there is more than one con to this system dude, its completely broken
I don't think this is a problem at all. It's a strategy that pretty much any competitive game has; attack the weakest link. Why fight against the good players if you don't have to?
It's no different than playing Call of Duty and consistently killing the weak players so you can get killstreaks to use on good players.
You even see something similar in action games & RPG's too. Do you take on the tougher opponents head on and make things harder for yourself? Or do you take on the weaker enemies first to make yourself stronger, therefore making those tougher bosses easier?
