Isn't the Biest Class Level 2 is essentially a more expensive version of L1 class? I'm trying to figure out what I'm missing. Aside from Fierce intensity (which, while nifty is something you pay for) the L2 class option is twice the base cost of the L1 class for +1A* with the same option to take 1 trait and a more expensive option to upgrade an attribute. Was the intent to stack an L2 class on the L1 like humanoids do?
*Since most Biests have a high base cost in relation to other races it usually turns out to be a rather expensive bonus attack.
