If you're playing as a Lv60 character by that point (which you should if you have imported from ME2 & done most of the DLCs) then everything goes down easy. At that point, even on "insanity" difficultly there isn't that much of a challenge.
But yeah, the Lancer still packs a wallop.
Presuming I'm actually any good at the game
I'm not sure what level my Shep is at off hand but for the one who has gone through the citadel, I guess she'd be around that mark
ME1 + bring down the Sky main missions completed
ME2 (all dlc and except for Firewalker all missions complete)
ME3 (completed - then New Game+ with all the DLC in).
For the party, I started off loud and just got louder so I missed the Shep/Grunt/Wrex conversation
@Angel4576 - Just got the soundtrack too. Thanks for the info
