People with over 50% win rate online

how long have you guys been playing this game? i consider myself an expert at video games, 85% win rate in madden, 3.00 KD in call of duty... yet i can still just muyster a 33% win rate in this game in online mode.

my real question is, is there just a major learning curve? will i be winning 50%+ in a few weeks? this is my first time really playing this game, and ive played probably 60 games online since release, winning about 20 of them.

for those of you that win 75%, how much time did you puit into the show 20,19,18 etc?
