There won't be magic, but the racial skills of the Orcs risk becoming an overpowered advantage in battle, compared to other races - if the descriptions of their "war cries" and various "rages" are to be believed... In short, there will be no stopping the Orcs. :D
In my opinion, Dark Elves will have the hardest time against Orcs, because in the case of the Academy, it is difficult (or impossible :) ) to predict what kind of magic they will focus on... but Dark Elves either focus on Chaos, or Chaos with Summoning, or (if it's Lethos) Darkness. :) It will be difficult for them against Inferno... I don't know what kind of magic Inferno will focus on (they can focus on any of the four ;) ), or they might not focus on magic at all, limiting themselves to Surprise Attack, Cursed Sign, and Haste. :cool:
