LOL I have never gotten past 8 and I am saucing these people. Level 50 OMG obligatory get a life. Maybe if it was that fun I guess but good lord man there are 900 other things to do.
Mine is from casual play not extremely agressive, and all around play as well. defence, offence, distractions, base building. grab the flag just enough to uproot it from its base and move it so someone else can get in. I dont need to be the hero the entire time. most of the people I have seen in the 20's or up are decent. not many are just padders getting points for more walls.
there is no reason you couldnt get 12 -13000 points in a game so you can climb the ranks quick. I got 16000 because the other team kept throwing tons of turrets down at us. that and my entire team just left the game so it was me and one other person. the other team could have easily won, but they were just messing around. (as was I without a team to back me up)
High 20's. I'm 18 myself, put in a lot of time last week or so but growing tired of the maps/players at the moment. I'm one of those players that doesn't really care about dying so I play fairly aggressive, yet when needed will play the base. Let's just say I play smart and pay attention to what is going on.
