Personally I rarely go over 12k, if anyone wants to waste the time going to 25k to be over me they are going to have to drop down to get me any way, why bother climbing?
Tactics? Bah! It's called being a wuss. You cant handle a fight on even terms? Where's the challenge in using 5-10k alt advantage picking lower cons?
Too many believe the number of kills is more important than the actual game which is combat.
