Every once in a while of playing online, I notice some people are in the game but they are shown as level zero. They don't have a templar profile that I may view, I can only mute their chat but can't block them (or any other action). It can't just be a first time player, everyone (AFAIK) starts at level one.
At first I thought they were just people who have just played through the tutorial missions and are in the post-tutorial game but some of them I've encountered have non-default ability sets. I've even found one level zero player using the Count with all the level three customizations (such as the headbutt stun). I'm finding more and more often now that people with "lag problems" (read: cheating) are people showing up as level 0 more than any other.
So who are these people exactly? Why don't they have any information on them?
