Wurms getting stuck while being pushed
 

Noticed this with the wurms before Doze, we'd be pushing them and sometimes they'd get stuck in such a way melee push didn't have any impact no matter which way we pushed

Yes it was near walls.

Also we found that you can push the dragons into the pillars in the Dozekar entrance area in such a way that their aoe would not hit the raid but melee could still dps them

They also can't be pushed on stairs at all btw. But yes, wurms (and dragons) have major problems with not being able to be pushed.

Happy to identify the more lucky than exploit pillars if a dev wants to see
