Yes, he would be the intelligence hero for them, or, if they have a second, one of them

And thank you, Cthulus.
Another Hero idea for the Uncorrupted Orcs:
Orc Commander: The Orcs are masters of commanding their underlings, and this guy is the perfect example. The orc commander's first ability allows him to summon 1 grunt permananelty, going up by 1 more grunt per level (this spell has a lengthy cooldown, and is deactivated after you reach High Upkeep). His second spell rallies his troops with a commanding shout, giving them bonus damage and an increase in attack rate and movement rate. His third spell is the Command Aura from WC3, unless, of course, you want a new aura, in which case, I propose Commanding Prescence, which is essentially the same as Command Aura, with, probably, some tweaks. His Ultimate is Commander's Charge, which turns him invulnerable for 10 seconds, gives him an increase in attack damages by 20%, increases his movement and attack rates greatly, and gives nearby enemies the Impressioned by the Enemy debuff for 2 minutes, which decreases their armor by 25%, their attack damage by 15%, but gives them and icnrease in movement speed by 30%.
