Well, just beat it on the Hardcore difficulty. Now to start up Insane difficulty with my level 30 guy. I think I might try a different class, I didn't even bother using the Soldier's powers. Maybe a Sentinel or whatever it is that has the extra shield boost. I think I might need it. As for the ending, despite the hype I didn't lose anyone, although I can see where the game designers would write them in if needed. All in all, a great game that I'll probably beat 4 or 5 times before getting tired of it (barring some kickass DLC) and start waiting for ME 3.
