There are lots of bmi people who want to be at home as many nights as possible; not really compatible with long haul flying.
I left short haul for long haul because I wanted more nights at home. Admittedly, I am a commuter so I used to bid for longer tours but even taking that out of the equation I have more days at home since joining a long haul fleet and, no, I'm not too knackered to enjoy them - quite the opposite.
