"Why can't I create a worgen in the beta?"
Worgen creation is disabled for a little bit while Blizzard changes up the starting area. We also hear Blizzard's doing a lot with the models. This is normal beta behavior for Blizzard; it won't be that way at release.
"Do you know if the revamped old world has quest completion achievements by zone as is implemented in Outland and Northrend. I would be much more likely to work on the new loremaster achievement, whatever it may be called, if I could clear out zones one-by-one and move onto the next. The current system of quests per continent is a sick joke, IMO."
Blizzard hasn't really revamped the achievements yet, so there's no way to know what's on the plate. The developers have expressed their own dislike of old-world questing achievements before, and I would suspect that this is on their list of things to change. The new level 80 to 85 Eastern Kingdom and Kalimdor zones have the BC/Wrath-style questing achievements, though, so that's a relief, at least (although they don't work properly at the moment and probably won't until release, if Wrath is any indication).
And for anyone contemplating working on the old-world quests right now or any loremaster achievements, I highly recommend -- nay, insist -- that you use EveryQuest or something like it. Just do it; it'll save you possibly hundreds of hours.
"How many skill points in a crafting profession do you need to learn the lowest recipe from Cataclysm? Do I need to max out my enchanting to 450/450 to learn the new recipes?"
Rhabella answered you in the comments the exact same way I would:
The new (but not top-tier) recipes will kick in at 425 then, or whatever the the magic cut off point is. That way you don't have to grind out insane amount of "old world' mats to hit 450, like you would have to now.The current system is set up where you can learn the new level at 25 skill points before you max. I would expect something similar where you can train for the next level at 425.
"Does anyone know how the Sea Legs buffs in Vash'jir interacts with the druid's Aquatic Form ability? Does Aquatic Form confer any advantage in the zone since its effects are largely duplicated by Sea Legs?"
I've heard they don't stack; however, I can't test this myself, unfortunately. Either way, it won't be that big of a deal -- at best (or worst, depending on how you look at it), everyone is on an equal
"Will WoW ever truly be a finished product? Just musings based on one of the answers, not a serious question, but feel free to throw in your two cents."
Very doubtful. MMOs are never truly finished; they are an ever-changing world that encourages dynamic content every step of the way. Even EverQuest, which was released in March 1999, is still getting updates. With 11.5 million people playing WoW, Blizzard will have ample reason to continue to update this game for a very long time. I know that it has long-terms plans (or at least general ideas) for Azeroth and WoW, just like any other multi-national multi-billion dollar corporation would have plans.
