Here are some old videos I previously posted and I took a look at them again.
Trakanon Raid (I believe this is Luclin)
This one is a bit inconclusive as there are people all over the place, but at a few points it looks like there is heavy position on one side. The interesting thing is basically Trak stands in his exact same position the entire fight.

Maestro Video is a bit more conclusive. It is in first person view but at some point a caster gets agro and entire raid force rushes over to him including pets and are all on one side, he barely moves.
Even when he is against the wall most people aren't pinning him perpendicular but angled and he push is very minimal. Could also reinforce a portion of my animation idea as he looks to move a bit when doing his spell casting and hit animation. If anything from the animation is causing push, it would just be 1 push value per animation, not adding push values from individual attacks.
This
Innoruuk video also is a bit inconclusive, but at one point the GFlux pushes everyone to one side and they charge back while Inny is near a wall, they are all melee and facing him for a significant period of time. Even if he is near a wall it should slide him sideways and he barely moves.
So yes, I do disagree that we are no spot on to classic after seeing these. Even if weapons being used are not the fastest as we have and haste values are unknown, the pure volume of melee hits should push more than they are if we are talking P99 push.
