I think 5E is by far the greatest edition of D&D. The basic framework is fantastic, and it easily allows for customization (which was a heavy emphasis during the playtest). The fact that I can ignore the "rulings" from the lead designer without having my game fall apart in front of me is amazing.He is 1 of 2 lead designers and he has a vision for his game that he is sticking to. You're not just seeing his design in his tweets, his design is the game.
The smart thing to do when you don't like a game is to not play it.
If you prefer another edition of D&D play that one.
I get it, the edition you don't like is the most popular of RPG of all time. I hated 4e so I didn't play it or engage with it. It was unfortunate for me that there was no new D&D for me. If it was wildly popular and poised to last for 20 years I would probably be more disappointed. I wouldn't think of the designers as idiots though. Or feel that I was owed a different game. Or bemoan people who do like it.
Move on, don't hate people for liking something you don't.
My issue with JC is that his "rulings" push the game in a different direction than I want for MY game. They may be better for the majority of DMs, but he knows nothing of my group, nor my DM style, nor my goals for my game. I do, which is why I often ignore his "rulings."
