I agree, plus the games balanced around Heroic, as far as I'm aware anyway. However, I still believe the Prometheans should have been stronger, a few of my buddies and I started going through the missions on Legendary and simply plowed through them. In total there were three of us, and we only had a total of one or two deaths per level. If I said this happened in Reach, people would laugh, with this game though, it's believable. The enemies are simply laughable... On a separate note, not necessarily pointed at you, I'm not totally convinced that the Didact is dead. If you watch the credits, at the end there's a cut scene with him talking about being defeated, but wanting to come back for revenge. I don't know about you guys, but that doesn't sound very dead to me...
