You are still applying an advantage EVERYONE has to only UD, a simple point you seem to be unable to grasp. A Halfling has a much better ability to pump from inside a FW than an UD, but I don't see you crying about that. Losses are irrelevant, training with gc is far easier than converting.
And again, everyone already knows FWing is an abuse of the system, continuing to say that is useless. But UD gets no additional benefits from it.
