I absolutely hate DLC that integrates with the main game and gives you OP weapons.
There was one game that the DLC gives you the second best weapon at the start, as a thank you for preordering. But I didn't preorder, I bought the ultimate edition. So wtf.
I find the DLCs / preorder bonuses that give you really powerful weapons at the beginning of a game just… bizarre? Like, okay, thank you for the thing that completely ruins the progression?
