I like D&D Next. There are a few things I'd like to see changed, but all in all it pretty much seems to be exactly what I thought 4th edition should have been in the first place. Personally I'm hoping that the final rules at least have the option of less hp, but in general there seems to be less than in 4e, so this is good.
I will be running a game, running the PCs myself, later today. However, I hope to find other players to playtest with as well.
