When going heat3/cold3 you also have to consider the extra +2 encumbrance: is it going to hurt you or your opponent more? Nations relying on thugs or a few elite units will probably be hindered more then nations relying on hordes of cheep units. As Yomi, heat3 might give you a defensive advantage against some nations since you should be mostly unaffected. I'm still not sure if it's worth the income drop though.
