I just can't really see the support for ArenaNet, honestly. If you think that lady is a jerk then whatever but that doesn't really change that ArenaNet has bungled this whole thing from multiple angles. It's bad management, it's nightmare PR, it's incredibly avoidable.
They're just not really to be defended here, in my eyes.
I felt it was a harsh move but upon seeing more of her character I have to believe it was right to part ways with her. I personally feel worse for Peter, as he was a 13 year old vet who seemed to be more polite pre and post firing, he just tried to defend a co-worker, that is where I think they bungled it a little. I have to wonder how much more was going on behind the scenes or if it was really just this situation that led to the firings.
How did it run on 360/PS3? The CPUs in the PS4/Xbox One are kinda weak so it doesn't surprise me if something physics heavy can cause issues. I'm sure this is mostly optimization related tho if the PS4 Pro runs it OK, as that has the same CPU or close to it as base PS4.
