Honestly, I can't say I would want to make a Reforged version of my campaigns even if they were to properly re-add the custom campaigns option. I am kind of insulted with how everything turned, not so much about Reforged itself as I don't care too much for it, I'm more disappointed about the original version of the game getting ruined along with it. But putting my feelings aside, I genuinely don't know if it would even be possible to Reforge my campaigns, and I'm saying that mainly because of the vast amount of custom content I used. All the custom models, skins, etc I used don't have a Reforged equivalent. So what's the option in that case? I doubt we'll see a community rally to make Reforged versions of those models again. The other option could be to use WoW RIPs, but are those even allowed now? If they are, they wouldn't even fit considering Reforged's art style isn't even similar enough. I was hoping it would go in a more of a WoW art style direction, but that was just a personal preference of mine.
I don't think there's a way to do it without making a version that wouldn't feel drastically different. The way my campaigns are now is more or less what I wanted to achieve when I originally decided to create them. I'm very happy with their current state (even though I said RotBE needs some changes) and I would hate to... "ruin" them, I guess. At the moment, I can't see a Reforged version being of my campaigns being anything close to what I want them to be. Regardless, thanks for sharing the message, Jayborino.
EDIT: I've always said I don't want to make anything I don't feel passionate about, so I'd rather focus my creativity elsewhere than work on something I know I wouldn't care as much about.
