I have been having this issue for more than a year now.
My GS skill 3 (swoop) only moves forward somewhere around 400-600 range (swoop should move players 1000 range forward with a leap and a jump, however it only gives me the initial leap, the following up jump never works.. because the jump only moves you 50-100 range forward at most...)
It is supposed to be a skill that has 100 range further than thief's SB skill 5 infiltrator's arrow (900 range)
However my swoop is only half of its (infiltrator's arrow) range when I compared it with my thief friend.
Only a little bit further than guardian gs skill 3.
I am not quite sure if it is just me or it is a game wide problem.
Anyway I hope this gets fixed soon!!!
