Nah, it's always been a part of the game - it's not a Homecoming thing specifically
It's not actual rubber-banding.
It's a rubbery feel.
Like there's a cast-time on all the powers - so there's a buffer or something - a lack of snappiness.
You know, it's like when you run miles away and around a corner and then 10 seconds later some power hits you.
Or when you shoot at a mob and your shot follows them around a corner.
Or when you do a knockback on someone who's getting up off the floor and it doesn't knock them down again.
But it's not rubber banding where people run forwards and then do the exact same movement over and over. That's not happening at all, the ping seems great, in fact!
There's something there that I, evidently, haven't defined sufficiently in the OP. Something that always felt a bit... weird.
