Somewhere about halfway in the past 3 battlegrounds I did, I suddenly couldn't walk or tumble anymore, not in any direction.
I was completely stuck in place.
Once this happened in the middle of a group brawl, and lasted about 10/20 seconds, untill I was killed.
Three other times it happened after respawning, and lasted untill the end of the match.
Being stuck at the spawnpoint was especially annoying, as I could not do anything remotely usefull for the rest of the match.
Seeing all of my teammates respawn out of my character was also not what I was aiming for.
I checked, and I wasn't stunned, immobilized, out of stamina, or any of such things that could explain it.
It's not my computer or mouse, as soon as the battleground was over and I was teleported back to where I was before I could walk normally again.
Has anyone else had this problem?
