That is something I started some time ago, and never finished.
Updated the Victor guide now, so that most camps have that BHG alternative.
Haven't done any summary for the troops needed though.
For camp 15 you would need crossbows, and camp 19 was the one I never found time to optimise,
so for the time being I will have to refer to SidV's guide,
or ask that you invite two lootspot buyers who each has a veteran to deal with camp 19.
EDIT:
Added camps 13/15 unblocked and camp 19 optimised for the normal generals as well... Enjoy!
