Yes, d and s endings would be my natural choice. And gotten is ugly, but I can live with its use given that it follows a straightforward construction that has its roots in Old English. But I do think that it should be considered idiosyncratic usage, as should acclimated. Alas, both are so widespread they are considered US standard.

I strongly agree with you that there are changes afoot in the language, but do feel that some should be stomped on. Drugged should be first set fire to, then the ashes stomped on ;-)
