They look nice enough, but how many options for the same generic fantasy troops / tropes do we actually need? Hopefully down the line the orcs / elves / dwarves will be interesting rather than just competent, but I'm not holding my breath.
I see your point, but I do think they're filling a good spot in the market. The reason I like these and the Oathmark humans are that they provide some solid options for fantasy humans that are not just historical miniatures being used for fantasy. As much as I like (and have use for) minis like the Perry WotR figures, I've also been looking for some non-historicals and I ran into a few problems. Barring "high fantasy" options like GW's Sigmarines or Mantic's almost-Sigmarines, most of what is available is a diverse mix of metal fantasy miniatures with no unifying aesthetic or scale. But these new plastics give a couple of options for bulking out a lot of rank & file affordably, with a big mix of poses (being plastic kits) but still retaining a unified aesthetic.
I do think that there's more generic fantasy available for some of the other races, though -- Northstar (again), Mantic, AoS and I think maybe even one or two smaller producers have covered a lot of the generic dwarfs, elves, O&G with recent plastic kits. Hell, we even have plastic gnolls now!
On the topic of generic fantasy tropes, I think we're still missing a "naked" skeleton kit at this point.
