Not every game is as tolerant of multiboxing as WoW. Have you researched WAR's policy on this matter?
The way I see it, multiboxing gives the person a tremendous advantage in PVP when focusing DPS with ranged classes. WAR being an extremely PVP heavy game, I can see the designers being a bit allergic to multiboxing.
And honestly, I can't see them bringing WAR's spec too far out of reach of bargain/student gamers. For such an expensively produced game with the ambition of being a WoW killer, they'd be killing a big chunk of their own potential market share.
