Sounds like 4e is a return to 1e/2e! Where the Monsters had different stats than the PCs/NPCs. Maybe they'll just give us INT for each Monster but not Str, Dex, etc?
Ironically, one of the first things I wanted from 4e was more of a unification of class, race, and monster HD... taking away the weird separation between an orc whose first HD is replaced by a class and a gnoll who has two HD neither of which can be replaced by a class. Maybe give one racial HD to everyone and have that maybe replace NPC classes, or allow any monster to replace some or all of its Monster HD with class levels.
Also was hoping that LA/ECL would be easier to use... so that Monsters would be more viable as player classes. Why do they need to have PC-breaking at will abilities that they won't use more than a few rounds anyway? Basically, I was hoping for a game where there wasn't any separation between "monsters" and "PC/NPCs"... everyone would just be characters. 3.5 went in that direction, which I liked (having all monsters feature LA) and was encouraged that maybe it'd go even more that way in 4e. I can see how the new system will speed things up, but it doesn't sound like it'll model stuff very well in a coherent system. Maybe the time savings will make up for it, but we had those same savings back in 1e and 2e.... is 4e in some part a reaction to the continued popularity of 1e/2e, C&C, etc? Is this a system designed to bring those people back into the fold?
