If it comes to it, we'll find some workaround for Trapfinding and Healing. When I say "we" I mean you, but that is neither here nor there.
Alas, this is the medium we work with. Is it any better or worse than calling dibs while seated on folding chairs? There you get stuck with the <insert least favorite class>, here at least you can make a bid for <most favorite class>... but there is the chance that you won't get in.
C'est la vie.
