This boss simply needs to be heavily nerfed. It's that simple. The mech's attacks are all extremely overpowered, with most killing the players in a single hit, even if they have high-level gear. Yes, the missiles can be destroyed, yes, you can follow a specific strategy to kill him by grappling onto the ceiling and whatnot, but if you make one, singe, solitary mistake while fighting this boss, you're a smear on the floor It's back to square one, and keep in mind that this is only the second boss in the whole game. Also, while we're on the subject of this boss, even if he isn't nerfed, I've encountered an issue where he stands next to the entrance, causing players to be killed instantly when they enter. A minor edit causing him to return to the center of the room perhaps?
