Well ... you still need some ground rules first.

But yeah, that would be my expectation aswell ...
Even tho, on the other hand, what else would you add if you would have all classes released since day 1?
Subclasses maybe, but they arent *THAT* different in this settings. :-/ So they would need to release story content ... or have whole EA dryed out after few weeks ... months at best. :-/
//Edit:
Still i cant help the feeling that last class released will have fragment of testing aviable compared to first 5 we get. :-/
Same goes with races that will be "kept hidden until full release" ... even tho when i look at depth of feedback Niara provided for Halflings, and absence of any changes around them ... it seems like it dont really matter. :-/
