Mesmer knockback from GS bugged?
Sometimes when you use focus4/gs5 and land an interrupt while pushing, the mob will trip and not actually move. This bug has been around for ages…
Also, not sure if it’s still present but if someone tries to push/pull a mob and the mob happen to cross your curtain during the pull, the mob will trip on your curtain and not move past it.
Same on yaks in wvw.
There are several bugs with knockback. Enemies can get stuck on miniscule bumps or slopes of the terrain. Sometimes mobs just rubber-band back to their position before the skill hit (probably only in lag-heavy environments like world bosses). Sometimes Bloated Creepers at Tequatl just fall over, and those things don’t even have any attacks for you to interrupt. I doubt any of those are mesmer-specific though.
The curtain is also notoriously picky, it tries to apply a set-distance “forced move”, meaning mobs can overshoot or fly at weird angles based on how the move direction is calculated.
