It's a shame for you personally, because you have a game you wish to play, but no one to play with. That is understandable. But it is nothing that anyone else (including WotC) needs to or should care about.But right now I can’t get players to adopt A5E because it’s not on D&D Beyond. It took a lot of negotiation to get them to use subclasses from Kobold Press. I know they'd just prefer to use D&D Beyond. And that sucks. All the DM-facing stuff is fine. I can use all the material from Trials and Treasure and the Monstrous Menagerie easily regardless of what tools they use, but if I offer up A5e next to D&D Beyond, I know which way they'll go.
That's a shame.
Neither WotC nor anyone else should care if a person cannot find other people to play their games with them. That's no one else's concern. And more importantly it's no one else's responsibility to make it easier for that person to find people. That person probably just needs to do a better job of making their game interesting enough to convince 3 other people from across the globe to try it out. I mean come on... in this day and age when a person has the entire world of players open to them in some form or fashion across any tabletop gaming platform from which to find them... if they can't do that? If they are incapable of convincing 3 other people to play whatever weird-ass game or version of a game they themselves want? Then that's on them. They can make a choice-- not a play game they really want to but can't others who care... or play all kinds of games they might not prefer, but which they can find innumerable others to play with.
