Right, this is my main point where the 4e simplified monsters is better. If you look at the stat blocks we've seen, you'll notice that all the monster's abilities have the name of the ability and what they do right in the stat block. If you look at 3rd edition stat blocks, you'll see that it just has a big block of ability names in the feats, the spells, and sometimes the equipment section. So, this turns complicated monsters or high-level NPCs into a page-flipping nightmare. It doesn't have to happen during combat, you can do it in prep time, but it still takes time and fairly meaningless page flipping and indexing in 3rd edition that it doesn't in 4th edition.Mustrum_Ridcully said:The usability within combat is very similar - though I note some exceptions: If you statted up a high level spellcasting monster, you would have a lot of "useless" spells - spells that don't matter when actually playing the game, but still cluttering the stat block... Non-Spellcasters are not that bad, though if you add to many feats for different combat maneuvers, you might still have a lot of information you need to process but won't use...
Plus, the other issue. Having run plenty of 3rd edition Living Greyhawk modules, as well as official WoTC modules, I can mention that if a creature has a feat, spell or magic item that's not in the core books, they have to include a description of it in the module somewhere, like an appendix. That means that you sometimes have to be moving between 2-4 different sources just to know what your monster does in combat.
The 4e version, with extraneous spells, feats and stuff not even listed, and everything else spelled out, is a much better way. It's admittedly inconsistent with PC design, but the tradeoffs are worth it in my opinion.
