Honestly, it works for me. If I have to run around, crouch, or blink strike to go invisible I will. Sure you have a hunter, too, but this is my playstyle and I've gotten good at it. I have all the time in the world to do the bridge section, so it's no problem going invisible when I have to. Invisibility is Null if the Deathsinger phase because it's timed. I usually switch to Gunslinger here to increase my reload and stability, but I prefer my Invisibility build. Therefore, any phase that allows me to use Invisibility is easy for me, and any phase that isn't requires me to use a playstyle I don't really like. I'm just saying, this is how I see things. I don't really care if other people disagree. We all have different strengths and weaknesses. At least this conversation is more reasonable than the guy down there who called me a cheater because I can walk through the 1st phase while being invisible.
