Nyss don't trigger Warpath. That's a big factor for why I don't generally bother with Minions for Kromac or a lot of Circle really: they are actively anti-synergistic with him and spending what can amount ot a fifth of your list on models that don't actually help you towards your list's main goals is a bit against my personal instincts.
I think the Feralgeist and Swamp Gobbers are the ones I usually reach for. Swamp Gobbers are pretty obvious. The Feralgeist is neat mostly since it has really good scenario use. Many armies simply don't have the time or resources to deal with a one-point solo like it. That said, it's kind of my, "If I can only fit 1pt.' model personally (I like Gallows Groves in groups of more than one, or they feel a bit lowish on redundency).
