people talk a lot about getting the mcelroys on critical role and whether or not they’d break matt and honestly? I think matt would be fine. matt has been doing this for many years of many different players’ bullshit and he actively enjoys it when his players throw him a curveball. (also he has a serious advantage that Griffin doesn’t, to whit, he isn’t their shithead little brother and therefore it is unlikely to be as fun to make him Mad.) he can run with whatever they throw at him, it’ll be great.
no, what I think would be the biggest problem is Matt frantically scaling his encounter difficulty down mid-battle as he realizes that he made an extremely bold assumption about their grasp on the mechanics of Dungeons & Dragons.
