1. Hammer Station isnt the easiest FP in the game, infact its the first really tough one
Hammer is a joke if you pay attention to the boss mechanics. The last boss's AOE can be interrupted, which reduces his damage output significantly. The adds have low HP and can even be tossed off the edge by a SI. You DO have to deal with them or you'll be overwhelmed though.
Now, Mandalorian Raiders is the first REAL hard FP in the game, 2nd boss is arguably overtuned.
