Doing the best imitation of myself
I guess I don't know how everything will actually work out yet. I'm playing in two campaigns with characters that won't likely be in the PHB (Sword Bard/Hexblade and Bladesinger). I don't know how they will line up with the new classes that come out. I suspect both of my DMs will just run with the old stuff and let people take new things going forward ... but it seems like it's going to be a mess. As I think about it, I suspect we'll just keep the existing rules until it's time for a new campaign. It is going to make for some interesting discussions as things come out.
