Tip: Don't Push

I am neither terribly good at nor terribly interested in poke battles.  I rarely take a gun with better range than a 301.  When my team is sitting up somewhere taking potshots, for an extended time, I'm usually just crouched behind cover waiting for the opportunity to close the gap.  I play frequently with a buddy who loves his snipers.  I find it frustrating, mostly.  Very rarely do his efforts lead to winning a team fight.  He might get a knock that we're in no position to capitalize on, usually, unless I've been able to work out a flank to do so.
