DRK, PLD, GNB gap closers: 200 potency, 30s recast, 2 charges, 15' range
WAR gap closer: 100 potency, 10s recast, 20' range, 20 beast gauge.

They are balanced because WAR can gap close much more often and consierably farther distance. Like when I play WAR, I can gapclose to a target as soon as I target them from across the field. PLD/DRK/GNB is that awkward distance where it feels like I have to get decently close to gap close that I might as well sprint.
