Doing this chain at the proper levels with level 25 IO's at 25 I found the final mission hard. Maybe it was my build, but I died when I couldn't pull one lieutenant when the groups had two in them while doing this at +0 1. Cortex hit me with a Dominate (91 damage) then a Greater Psi Blade (320 damage). The virus decided at that point I was going to supposed to die since it hit me with a hold. Didn't help he spawned in a group.
Edit: After writing this post the instance reset and having to reclear it.
Edit 2: I was today year old when I learned I could cheese bosses using elevators to make them a little more bearable. Had to do that quite a bit on the Cortex fight. Beat it finally.
