The gamespot and gamespy pieces from yesterday seem to be a bit at odds with each other on the minions. The Gamespy one briefly mentions 3 seperate types of units which heal, repair structures and buff units/generals, of which only 1 matches the Gamespot archetypes given.
A screenshot accompanying the gamespot article also shows the options relating to minotaur captains, siege archers and high priests in the crystal of health menu so that pretty much confirms their presence too. Yet another screenshot shows Oak's "spirits", complete with health bars, and I wouldn't be much surprised if they were controlable, if perhaps temporary, minions too.
I'd guess either gamespot got a different build sans the extra minion choices or (probably more likely) the author got/gave the wrong end of the stick and there are only 3 units common to -all- generals and the other varieties are demigod specific units. Well that or siege archers repair buildings and minotaur captains give out buffs, it's a possibility I guess.
Plus the gamespot article spells the healer-ish general "Sepna".
That's just shoddy
