I ran my striker the week before last all weekend for trials. Same build and same guns. I found out pretty quick that there were certain builds and classes I would lose to more often then I would win against. Took down a 2400 ELO team carrying, but lost to a team with the same ELO as the guy the others were carrying. I'm starting to think my inconsistency is that I'm not changing my class build to react to others.
