@Sophrus Oh, I'm terribly sorry that my character's interaction with yours has made the game less fun for you. Oh, wait... our characters have never interacted, and mine has never done anything that has in any way affected yours. Huh, guess I don't need to apologize for that one.
@BCTheEntity And I'm sorry to tell you this, but you're under false assumptions. Urgrugg has hardly any control over them, at all. He considers himself 'in charge' because he's an ork, and orks think the one who's biggest and strongest is in charge. You've also made a mistake in believing that daemons are some kind of super-warriors. The daemons he's summoning will consist of pink horrors and bloodletters, both of which fall in line with veteran guardsmen in terms of combat proficiency.
And, to everyone, two things;
1.) This isn't something that just Happens. The ork isn't snapping his fingers and suddenly daemons are everywhere. He summoned two, and that's tapped him for a good while.
2.) Daemons summon daemons. It's how armies of daemons become a thing. You summon one or two daemons, which any random group of four or five chaos cultists is fully capable of doing, and boom... daemon army happens. The amount of power any given psyker has is completely irrelevant when it comes to summoning, because daemons being in the material realm leads to more daemons coming out of the warp in that area.
Just because everyone wants to play Batman doesn't mean everyone has to jump on the guy who wants to play Aquaman for being 'too OP.'
