I played siege on EU2. There were only a few guys on the server. But the most time it was balanced enough for a multi.
But you need a good team if you want to win with such a small amount of player. So if you kill a lot of enemies, but you need to do that nearly alone some people are getting angry...
In one round my team defended the flag quite well (teams about 6 vs 4 (varied)). A few seconds before the end of the round Mordhau went to spec and we had a small discussion:
That's intentionally multi-killing. Is it ok, banable or only bad style?
