Kind of an odd thing to say, since Critical Roll could have learned their stuff by watching us play in the 1980s.
Whoever they learned from were poor teachers. Mercer homebrews way too much and their stories are just awfully written. Their popularity is very alarming though and will cause great harm to D&D in the long run...they are bringing a lot of people on board, new DMs even, who never properly learn how to play. Combine this with the way WotC is handling the D&D IPs and the sad reality is we desperately need someone to step in and save 5e the way Pathfinder 1e saved D&D 3.5e before 4e which forced D&D to be better and step up their game. But everything revolving how modern D&D is being handled and popularized is all wrong.
