Can we get back to whinging about CW now, as opposed to whinging about 3.5E?
Impressions about the prestige classes:
It looks like they've copied a lot of the flavour text verbatim from S&F and other previous sources. This is sometimes unfortunate.
The cavalier, for instance, is still described as the "quintessential knight in shining armour", but it's still just a guy on a horse. It's an uber guy on a horse, mind you, but only the most literal-minded would take that as the defining essence of the phrase "knight in shining armour".
At the other end of the spectrum vis-a-vis literal-mindedness, the order of the bow initiate is still concerned with Zen waffle about truth and whatnot. Although it's been toned down significantly, and they've majorly reworked the mechanics so that it's no longer just a souped-up machine-gun archer. The end result is that the flavour text now has some (barely discernible) relevance to the class, which is good.
The new OotBI is also severely nerfed compared to the S&F original. This is perhaps appropriate, since the original OotBI was by consensus one of the more broken classes around; however, IMO they went a bit too far. I can't think of many situations where ranged precision will be useful, and the Sharp-Shooter feat is rendered totally irrelevant by Improved Precise Shot.
The kensai is utterly dumb. The class isn't so bad in game balance terms, but for ghu's sake, what on earth does it have to do with a kensai? It's nothing like a 1E kensai, or a S&F/OA weapon master/kensai. Even the underlying schtick, that of a character devoted to a master or ideal, has precious little to do with historical/folkloric kens[e]i.
The ronin is also pretty dumb, albeit not as much as the kensai. Again, the mechanics aren't too bad, but it's basically just a fighter/rogue wearing heavy armour. I wonder who decided that the concept of a wandering, masterless adventurer working for pay was unique and flavourful enough to base a prestige class on. At a guess, I'd say 99% of PCs are wandering adventurers working for pay. It's completely pointless.
A great opportunity was lost when they declined to name the master thrower as the master tosser. Oh yes.
The new bladesinger looks pretty good though. It's a pity they needed three iterations before they finally got it right (T&B, errata'd T&B, this one). Some reckon that it's weaker than the DMG arcane knight, but I think it's a tossup.
