I have timed all of the Rank 3 and Rank 4 champs that I have in ROL. No synergies, no class advantage or disadvantage, and no ouchies. Just vanilla fights, to see how they did.
This started out as "I wonder what underrated champs can do against the 'top meta' champs", which then spiraled into me just testing every single champ. Most champs went against Winter Soldier or Captain Marvel, a hand full went against Juggs if their abilities had a work around his unstoppable. Only one did I test twice, Apoc. Once against Rhino (no ramp) and once against storm since his abilities grant him a lot going against another mutant and that's not class advantage or disadvantage.
I only took each champ through one fight, I didn't do fights over and over trying to get the lowest time unless just everything went wrong and I thought their time really misrepresented them. A few champs really surprised me. I tried to play each champ with their best playstyle and equipped with their best relic. Take this list for what it is, a vanilla fight in ROL from some bored guy. This is just for fun!
If you see a champ that just did not perform any where near what you expected, let me know who and what playstyle you have seen them perform better in, I'll give it a second try.
I hope the link works. I hope you all enjoy!
