Controller all the way, mouse and keyboard feel like masochism! I'm fighting Genichiro at the castle, it's right around the middle of the game (I've watched all the spoilers). The fight's amazing, it's so precise and diverse, by far the best Soulsborne fight for me so far. I still have trouble with jumping to counter things, so I'm dying on his last phase. I'm getting pretty good otherwise, though.
Couldn't learn jumping on Lady Butterfly, sidestepping her just felt strictly superior, and the jumping guys at Mount Kongo I stealth-killed.
