Potemkin is pretty ridiculous. For some reason he is a bit downplayed imo by the general public but in my eyes he's pretty obviously a top 5 character/top tier. He's not as easy to pick up as some of the other top tier but I think he has all the tools to beat everyone and he's also strong against most if not all the other top tiers.
This has become one of my favorite fighting games ever. It's amazing and the netcode is great too. I honestly didn't think I would be grinding a fighting game ever again after MK11 but I find myself playing Strive a lot and watching it a lot and just enjoying the game without being too salty about it lol.
