Which is reason enough to consider them bullshit. When an entire faction is pretty much reliant on one troop for their kills (especially one with as much variety as Cerberus), you know you're dealing with some major league BS.
Spot on. That is one of my biggest issues with Cerberus. They have the most variety among the types of enemies, and the nature of their offense. Yet, 90% of the cerberus game is phantom spam, with atlases to fill in the gaps (and the constant smoke throwing, ughh). Probably one of the reasons why it feels like Geth have the most variety when it comes to actual gameplay.
But even without phantoms, cerberus would be the most annoying faction for me.
