As others already stated. The difference between Bismarck EM and T9 is, that Bismarck EM is faceroll primal that has been already cleared by anyone who has 2 hands while T9 was and still can be pretty challenging and well thought fight.
And honestly if there were only fights at the same difficulty like Bismarck EM there would not be any raiders/statics etc anymore, because there would be no end game content for such people. By the way there werent so many mechanics in T9 and the guides had under 10 minutes.
