ok. well the only floating helmet i've seen is the yellow hood, which when i asked people in game if it was like that for anyone else, a couple people said no it was normal on their screens. i chalked it up to submods i'd installed/uninstalled. dunno if there are any other floating helmet issues, seems like a minor bug that could easily be fixed. or not, what do i know. not gamebreaking anyway. floating heads, i've not seen at all.
the error messages during load are annoying, but have no impact as confirmed by devs. i've turned them off on my end anyway, so don't even see those. if someone new sees them and asks chat what they are, they'll hopefully be told the truth, that it's nothing. more likely be trolled and told to press whatever key combo it is to shut the game off. this community and any newcomers associating it with mbg is more of a concern than slight bugs imo.
i haven't seen anything like 10v25, though there's never more than 30 people in na since i've played again recently. haven't seen anything crazy like 5v20 in those cases. but even in eu, i didn't see anything like that. might be pretty rare and inconsequential. dunno though how often it's happening, but newcomers will likely not notice anyway being too busy being scared and trying to survive.
i think the mistake here is equating what you think a newcomer will be thinking with what you/oldtimers are. also, thinking that there are new players at all. are there? enough to matter? i think you're putting far too much emphasis on this one point you've been hanging onto. i don't even know if it's because you even believe it, or just a personality issue where you can't let things go and must argue for the sake of arguing. based on your posts, i'm more inclined to believe it's the latter.
