+Watch other good players.
+Stick to few "builds" till you get used to them.
+Do you a favor, use hotkeys. Try with grid configuration, use autohotkey to bind the keys to your liking.
Start using some abilities and control groups, and then slowly start to add a few more.
Finally, what mode do you play and what´s your ranking at the moment? If you win more than 50% you can easily be top500 at the moment. If you are between 55%-60% you can easily get top200.
Yeah, that's pretty true. Just know what kind of builds people are doing, set up some defense or harass/deny their builds and it's pretty much game.
I've been playing CoH since 2006 and CoH2 off and on. I don't really play as competitively anymore but my win ratio was around 75% when I was playing 1v1 and around 60% in 2v2. I don't have time anymore for CoH but it's still fun to do some team matches whenever time allows.
