That's it? What's the point of promoting?
Oh and Grissom Academy on Insanity makes me

For the people who want to start from scratch I guess. I've thought about it a few times; it can get boring playing with a maxed out character all the time.
And the rest of Grissom isn't too hard, it's just the atrium where you have Guardians, Engineers, and Centurions on all sides with no way to keep from getting flanked. You know it's bad when an Atlas is the LEAST threatening thing on the battlefield.
And the fact that Garrus keeps trying to hug guardians and turrets for some inexplicable reason isn't helping either.
