I'd go for a 50-25-25 split.
The problem
with drama is the fact that any good packet probably
needs at least one question that is Shakespeare-related
- as such, drama sort of has an absolute minimum
that poetry doesn't. I'd be quite surprised if an NAQT
or ACF tournament didn't have at least a few
Shakespeare questions, and its omnipresence sort of makes
questioning what else should be combined with it strange.
