The first time was very very memorable for me. The gear me and my teamates took were really similar to what the invaders had so I legit had trouble knowing who was my ally when there was a riot and my team went invisible. Legit pure chaos.
I'm not so sure on repeat playthroughs however...... Unless you get god tier weapons to deal with the summons it's pretty damn difficult.
I don't think he should be nerfed, but at the very least the fragment drops from the invaders should give you like 30% more health.
