Hordes variant

This variant idea is mainly directed at DK because he mentioned that when he fields an army that has hordes he deploys all the hordes he can get. (Sort of a voluntary handicap?) I wondered what he (and the DBA community) thinks of counting points as a variant. Any normal element is 2 but a horde is 1. So the number of hordes permitted is doubled. In terms of historicity I like the idea because horde-class foot generally did clutter up the battlefield. But then you'd probably have to tack on other HOTT-style rules such as buying in more hordes...
