I thought DOW were just mercenaries for hire, meaning you could use them in an army... or are they an army entirely on their own?
I do love the models, some are great to look at and some make great alternative models for other units, just to add some variety or to make them a stand out unit.
I wonder what Storm of Magic will bring... since it's bringing new mages and monsters I wonder if they will be army specific or usable by any army. I'd love to see some Lizardmen units... since it's 3 years since their codex and still no Tetteo'eko or Lord Mazdamundi. Perhaps a Arcanadon or Thunderlizard.
Either way.... I'm sure there will be monsters usable by all, or at least one for each army, otherwise it could really buff already powerful magic armies like HE, DE and perhaps Lizardmen (They are nothing compared to HE/DE and so on).
