Yes it is. You plan the same plan every time, and no matter what it works. Have you even played it since day one? The boss is a rocket/bullet sponge, with nothing but Nightfall tier enemies around him. You carry acid around systematically. It's based on team work far more than LONE cooperation. You could have easily gotten carried. Have you ever carried someone 31 or 32 through Skolas? Doubt it. Even if you did, still not really that impressed. It's a predictable ai. For you to say "you don't play PvE" is inaccurate like hell. My Grimoire and achievements have beyond proved that.
