I'm sort of addicted to manoring. If I xp I want to be able to manor. Preferably 4x mobs. My question is this. Is there any mob you would not seed because the drops from it outweigh the gain from manoring. One I never seed are the bug bears (1x hp) that drop brig helm parts.
I wouldn't worry about what the mob drops, chances are you'll make more manoring in less time then it takes you to get that one drop. I seed mobs in FoD and VoS even knowing the drop tables are not too bad, but the more materials you manor, the cheaper everything becomes to craft.
