Last of Us and SotC are two sore spots for me too. Even before DLC, the Last of US multiplayer shit was fucking grindy and obnoxious as fuck and I noped the fuck out of it without even doing anything other than what I got in one time through the main game so I'm basically sitting at like 14% or some shit. SotC I literally ONLY have the Hard Time Attack one to do but they fucked the controls on the port (PS3 at least. Not sure if it was better for PS4) and the gripping is buggy as hell so doing the one with the giant sword/pillar/stick thing that you have to run up at the start is complete bullshit and I finally gave up after multiple hours of fuck ups that weren't entirely my fault that kept me from getting it.
Did the same as you on DuckTales. Made a couple attempts at it but it was WAY too frustrating and didn't feel worthwhile in the end.
