I'm not certain that delaying would necessarily have done much good for Concord either. Maybe they could avoid the game becoming an example of how not to design characters, but I think even then it would still last about a year at best before players dried up.

I did hear that somewhere on reddit that there is an ironic following that's trying to do a fan server for it, but I don't see much point without them doing severe reworks to everything.

Maybe, but we'll have to see what they actually do during the delay. Plus, the internet being the internet, even if they do improve things it's likely a lot of people will just write it off on full release since the initial reception was so poor.
