This NEVER happened PRIOR to today's patch, and now sometimes you can wait 30 seconds to 1 minute or more for them to spawn. You defeat the Drow and get to 16% progress, then have to WAIT for sometimes a minute or more before the next GROUP will spawn.
It's very annoying, cause many don't know what's going on...
In the last Proto Engine Heroic, we waited almost over 4 minutes, and I'm not sure if they are reappearing at all??? Something seems to have GREATLY delayed the enemy DROW from respawning.
=======================================================================================
UPDATE: Seems what happens, rarely Wizard's are pushing the Drow with REPEL; then they are disappearing and not RETURNING. Someone needs to FIX this so they can't be PUSHED out of the room where the HEROIC is. And also ensure all Drow are spawning in the proper Heroic's area within a few seconds of earlier Drow being defeated--and keep them in their area like before.
What we noticed last night is that it isn't just the abilities with knock back. Some of the mobs are actually spawning outside the area and the companions can go through the walls to fight them. They often get stuck in areas inaccessible to players until the mob dies or the companions all die. When everyone has augment companions it's less of a problem.
Also, the pit boss yeeted himself right out of the room at one point. That was pretty frustrating. We could see him but couldn't target him because we couldn't get up to him. Eventually we all left and he spawned back inside the room. But the Proto BHE really needs to be addressed, it is thoroughly messed up.
I was also there when the Pit Boss Spawned, later disappeared outside of the Room, yet I didn't actually see where he went. Finally got a screenshot showing his WING clipped thru the outer wall partial above or on the roof. Sadly the Drow you won't see on the roof, or when they don't spawn inside like they did PRIOR to the 9-19 patch.
Note: at 16% to 88% there is often just 1 Bruiser that seems to SPAWN on the other side of the WALL, it can happen 1, or 2 times yet you can RUN around and DEFEAT HIM though--but you got to LOOK for him. Sadly, sometimes you can't FIND the 1 Bruiser on the outside, then you got to find a new instance.
BOSS DISAPPEARS and appears OUTSIDE or on ROOF.

Note some of the Drow also appear at ground level just below where the Demon Boss is, this started with 9-19 patch.
