The subject says it all.
There's a druid of 4th level, and in his natural form he is missing an arm. Is the corresponding extremity (a paw, or a wing) still missing after wild shaping into an animal (a cheetah, for example)?
I don't need an advice on houseruling, that is not a problem. What I need is a quote from an official source, explicitly and in no unclear terms stating whether the missing extremities are still missing after the transformation.
I know that under 3.5 rules it was explicitly said that the new form is an average, healthy specimen - under pathfinder rules there is nothing about that. The passage about generic appearance is not clear enough for my DM.
Unless otherwise noted, polymorph spells cannot be used to change into specific individuals. Although many of the fine details can be controlled, your appearance is always that of a generic member of that creature's type.
His argument is that this quote contrasts generic appearance with impossibility of change into an exact lookalike of a specific specimen, and, as such, does not state anything relevant to the question.
A missing arm in this case is a narrative device without explicit mechanical penalties except inability to perform actions requiring 2 hands. A missing eye would incur some clearly-ruled penalties, as a missing leg would; does that change something in the wild shaping rules department?
