Basically people can kill Turrets over and over with no DR on the kills.
Capping out valor rank 100 in a short amount of time.
I am sure this is on the radar of BW (I would hope).
Question is what will they do?
Ban? Highly unlikely
Roll back all valor earned since 1.1? Highest possibility
Nothing? Would make alot of folks extremely mad
