I figured I could share some of the cheesiest paths and fights I've found in 8.4.

First up: Miles Morales cheeses through the 8.4.1 path that starts with Gambit (and is great for the America Chavez boss as well). What makes this path tricky is that all specials are unblockable all the time. Luckily, Miles just...doesn't care. Every special - along the entire path - will miss him 100%.
Unless you do what I did and accidentally pull of a well-timed block against one of the specials. That's the only time he will not try to make an attack miss.
He also makes the America Chavez boss a cakewalk since she can throw as many unblockable SP2s at you as she wants. Just a small PSA, though: striker hits grant you extra fury buffs to fuel the Rising Sun node.

This does require some decent AI cooperation but as long as the defender puts up their block after you get a 15-hit combo and doesn't charge at you, you'll end the fight
really quickly.

This level of cheese only really works against Old Man Logan on the path since he has insanely many buffs, but I might try to do a showcase later of the rest of the path. It should still be interesting, but I haven't tried it out yet.

The crux of the path is that the defender has a 90% chance to evade basic attacks unless you have a precision effect of some kind on you. You could just intercept the opponent in order to get a precision passive that way, but there's also a node that gives you a teeny tiny precision each time you gain a cruelty buff. Luckily for Vox, he gains a cruelty buff on his first light attack. You can shut down the entire path with one light attack. It works for the entire path, and Vox is additionally poison immune, which helps a lot against some of the defenders.
