If you were playing a non-caster, eg monk or rogue, and a wizard offered to PTP your character into a doppelganger, and if you could perfectly replicate your old appearance, would you accept? Assume, for the moment, the no-reversion ruling. (Not that I care much about a rumor of a Twitter message, but I do care what the DM allows.)
Could you subsequently acquire caster class levels, or any levels at all? If you're the awesome impersonator and spy, plus stats, HP, AC and a big unarmed melee attack, but *you can't ever progress again*, then I'd have to say no thanks. There's also the argument about class abilities, feats, etc. and whether those are limited by the stat block of the new form. (Meh. If PTP means you lose your proficiencies, then you might as well also lose all your languages, and at that point you don't really have the same personality, IMO.)
