1. The wording regarding skills of a Synthesist Summoner (I know, another question about what is the most complicated archetype ever) seems a bit vague. I can see that the Synthesist would not gain the eidolons skill ranks, since that would give you a large pool of points. What is less clear to me, from a logical standpoint is the question of whether you would gain the eidolons class skills while fused? It seems logical that if eidolons have perception as a class skill, that you should also have perception as a class skill when you are fused. Could be wrong, but the wording of the ability seems vague to me, and it seems there is a lot of debate on this issue around.
2. If a Synthesist Summoner chooses the Quadruped base form, is he able to cast spells while fused?
