Rob Schwalb, one of the lead designers of D&D 4e, had a blog post where he basically says 4e catered way too much to the munchkin math geek crowd and he's glad that 5e is going back to its roots, where the impact of the number-crunching min-maxers should have a much lower impact.
Reactions to this blog are interesting. Over on The RPG Site, it's been mostly positive. A lot more old school D&Ders post there than you might expect.
The reaction on RPGNet is the complete opposite. They are raging about this. They HATE that he called their pet D&D version basically a bad game compared to its predecessors. If you have an account there, don't make the mistake of defending Rob's post, as you will probably get banned. (Not that the mods are biased or anything).
Please take the time to look through both. If you have only been active on RPGNet, I strongly recommend you give The RPG Site a chance. The forum runs a lot like RPGNet did 12 years ago. Mostly gamers, with little moderation.
