GiffyA lot of newer players have the problem of burning themselves out by warming up to much. Honestly 5 min in DM and you should be ready to go anything over 30 and you're risking it. Other than that just continue to play and with time you will get more consistent.
Sorry for not being specific. My warmup usually lasts only a few minutes (never more than one map of dm). I understand where you're going at, though. Also, I'm not new O.o
reillyHappened to me too when I started playing scout. It happens less often the more you play, but it takes a long time to stop.
Oh. Wish I found a way to break out of it though. :(
