It happens regardless of mech class, at least in my case. I play B most of the time, and stuttering is unpredictable.
Sometimes I get slammed to the ground while trying to jump, or teleport while dodging, or just plain phasing around while standing still after spawn.
Yesterday I had 92 ping which never ever happens, even on Amsterdam. Missing or delayed sounds and animations are also more frequent.
I used to rely on audio cues to manage breacher shots, now it is pretty much guess work.
Damn this is annoying.
