Wasn't too bad for me surprisingly, one of the few missions I only died on once. What class are you? Because any class that's better than mine at combat (which is Engineer) should probably be totally fine with it.
I'm an Adept, so I'm pretty powerful at this point. Most levels, as long as I can get decent cover, I can tear through. Problem I have with Collectors is the Scions. Anytime I have to face those guys things get dicy for me. But it's good to know you managed it with an Engineer, since I consider them to be the weakest class in the game. I've still got to do another loyalty mission before the game allows me to go on the suicide mission, so I need to figure out which one I'm willing to spend my time doing.
