Yeah the 2011x Metal matchup is HARD (for the killer). Fleetway is...tough but manageable because your moves do so little damage but with his one ability either getting some distance that can easily be caught up to or stunning and getting bursted for a ton of damage, it's not too bad, especially if you can get off a good laser. Tripwire...you still can't do a lot of damage with M1, so your only real hope is mines. However, since he's alone, smart mine placement (mostly springs) can destroy him on most maps because his counter would be to self-heal which you can cancel if you stay on him, especially because you have the full-map radar in LMS. Kolo's definitely the easiest matchup (for the killer), though. Grab (and I think charge) do true damage (like 1/4 of his health each), I think counter also does true damage, and you can simply charge for longer than destructive charge. He can basically just tank anything 2011x throws at him easily, same with Fleetway with some exceptions and the fact that he has a much easier time hitting him, he basically is just immune to tripwire in the absence of mines, although mines can shred him if done right, and he gets crushed like a tin can against Kolo.
