Ugh, no. They arent going to ditch the streamlined system to go back to the most unbalanced and bloated system in D&D's history. 3.5 is dogshit for vets too. I wasted an hour of my life adjudicating a Mordenkainen's Disjunction dropped on a great wyrm red dragon and the PC party, with the cascading buff effects, stat adjustments, etc. I had run the crap system for over 4 years.... Never again.
