As someone who has fucked up similarly before in a different context, both of those things happened. I got put in my place, we agreed I was going to adjust my attitude, ate my warning, and the outward conversation was that the problem was resolved and we’d work on being better in the future.
Changing the character designs wouldn’t require an all new game. If they can come up with a signature gamemode and better characters, they could have some moderate success.
TBH I had a look at Deadlock’s characters as well and frankly they’re not that inspired and interesting either, but people really like that game because of how it plays. Still that’s in early development so the characters could improve. IMO if the Concord devs make the characters hot, people will pay and play. I’m not saying that’s a good or bad thing, just what I think.
