So Gunbreakers LB can be interrupted. Was pushed back far against a mechanist or monk one of the 2 while using my LB on the Crystal in CC. Dancer also disabled my Guard ability, and outside junction and targeting a tank (good luck if they dont have a tank) you have 0 defensive cds and dont pull enough damage even with junction dps to compete with other DPS.
Also not only that but when i got pushed out of my LB, i was unable to use any abilities at all while i was moving away to heal. Couldn't cast heals, or any other ability while i wasn't silenced. So thats also a bug or "working as intended" since pvp seems like a dumpster fire.
