Gotcha, thanks guys.
Neither the case with and without errata seem like optimal solutions - I spent a feat for my PC to be trained in Stealth without really being aware what sort of mess it was, it would seem.
Offhand, Ata's proposal sounds good to me: No stealth with light concealment, but ok with light cover.
Yeah, that's because rogues do need CA to function as strikers at range.
Id give it a penaly of -2 and make it necessary to have moved at least 1 square if already hidden(I'm talking about light cover here).
