I was someone in BF4 who made a lot of EMBLEMS for myself, requests from players/squads, and even some companies and pro teams. I rather enjoyed making them when I was tired of the battle grind. I too would like to say I hope they return. I dont know what resources EA is putting into BF 6, but id think AI could be a useful tool to keep emblems from getting out of control like before. People could petition false positives on innocent emblems the AI may have made errors on. Petitions Id assume could be handled by staff. As for people who think its OK to keep making idiotic emblems, I'm pretty sure a suspension for willful misconduct would make them think more about doing it.
Maybe thats a little out there but its just my 2 cents on it.
