Not sure if folks have read this, but a long thread has developed on Enworld in response to info presented on the early playtest rules. Granted, it's an early version and it's still early in the process, but the spirit looks very min-maxy to my eyes.
Too funny, I'm reading through the comments of the whole post and the feeling seems to be it uses lots of 4e mechanics without actually saying so. To the point that one commentor wrote:
"It's like they're [WotC] willing to sleep with 4e, but not willing to be seen in public with it."
Too fucking funny.
