4E Random Comments

I've had the books now for a week now and I've been reading them when I can. Some random thoughts in no particular order follow:

• Alignment: I'm cool with the alignment changes but the naming is wonky. It's obvious now that they kept the "corner" alignments and renamed "neutral" to "unaligned". Presumably CN has been rolled into "unaligned" and NG was merged with CG (though just called "good" now). Not sure about LN, but I'd guess most people ended up playing LN as LG or LE so they didn't see a need for it, and NE was probably absorbed by either LE (now "evil") or CE. I'm OK with the changes, but why call CG "good" rather than "chaotic good"? Or he opposite for the evil alignments? The implication is that alignment follows a linear model, like the first edition of WFRP, like "LG-G-U-E-CE", whereas it's really a square with U in the middle. Not sure, but not a big deal.
• Disease: Actually more complicated than 3.x, but a lot cooler. I also like the idea that if you roll poorly enough on your Heal check when performing the Cure Disease ritual you could actually kill the person you're trying to cure.
• Masterwork armor: Seems a little odd, but you can get by with the mundane for quite some time. The "second tier" armor is no more weird than mithril and adamantine (and you can't get it until level 16), and from what I can see you wouldn't be dealing with the "third tier" until the late 20's anyway, at which point you're wearing it to have dinner with the gods. In any case, they're all just sets of numbers so the names and fluff are easily changed.
• Skill system: In 3E, the idea was good but I always felt the implementation was flawed. I much prefer the consolidation and static increases of 4E.
• Opportunity Attacks: From what I can see, only three things provoke OAs: ranged attacks, area attacks, and movement. I may be wrong (I haven't fully read the combat chapter yet), but a definite improvement if not. AoOs were something that seemed like a good idea but their implementation took more away from gameplay than it added.

More comments as I finish the books. I've skimmed all three but I've only been thoroughly reading the PHB so far.
