I'm just gonna do a brief vent... please don't read onward as what follows is completely pointless negativity.
I played some 4e; it really sucked. I'm glad it is dead (or at least dying).
When I played, all the players wasted too much time building characters (mechanics only) and analyzing feats and powers DURING COMBAT and not enough time doing anything interesting or creative. Combats, and to some extend the entire game, felt just so frikkin procedural.
I'm glad there is a new edition coming out for no other reason than some kind of satisfaction I feel with the burying of 4e.
I hate 4e especially for making 3e seem like such a good system in comparison - I hated that one too (also mostly because of all the feats and builds and min-maxing).
