HS gating mobs
 

When killing "a helot skeleton" outside of Drusella's room (pather), it was gating directly on top of it's spawn.

Gating was changed a few patches ago. Mobs that are near their gate point should not attempt to gate at ALL, and that was indeed how it worked on p99 for many moons. In fact, you could cleverly duo some """hard""" enemies like Vaniki or Kael temple by utilizing this strategy.

Pushback was changed too, to a bizarre amount. Both on Live back in the day and here on p99 back in Kunark, you could push VP dragons so far with proper tactics to prevent any gates or CH with as low as 20-30 people. Like, you could push her basically halfway up the ramp. Again, this did require using the proper procs and a guild that understood if even one person was counter pushing, it At this point, my best advice re: stuns is - good luck.
