Is this support bugged? Or is this a glitch?

I was playing a normal match and got 1 kill perfectly fine with no lag. Ran accross the map and came across a support that didn't spot me. Shot and shot didn't register. Is this what everyone is complaining about when they come across a support?

It isn't just supports, it's every class. It's lag related. Recently nearly every server has been laggy. I'm starting to think the only capable host is one using fibre optic...

This match was no where near laggy not one bit.

I have to say that is the first time I've even seen that. Pretty weird.

This is EXACTLY what everyone has been complaining about.

I'd bring this to the devs attention. Because of how long you and the Support are able to track each other, and he is able to target and damage you, this is either a glitch or a bug, not a lag issue.

The game doesn't have to lag visually for this to happen, but I'm sure a dev related this o connections and lag.
EDIT: check official issues list sticky - it's in there and lag related

Just to clarify for the 10th time in this thread. it is lag related but it doesn't happen very often. It does get really annoying when i'm the support and i unload my shotty but it doesn't do damage.
