I swear I saw this somewhere else, but just in case…
How about having higher level unreleased Clearance Levels change the PvP from a 3* into that character’s current 4* reward?
So if Blade PvP came up, and you chose CLX, it means you at with the 4* Blade.
Doom switches to Invisible Woman, Torch switches to Thing, and so on and so forth.
It kind of sucks that all the 4* PvP is basically gone forever. Especially now there would be people with fully covered characters to play with instead of loaner-geddon.
There are also drawbacks to pushing everyone to play at the 4* level.
Is a Clearance Level switch over a fix that could be implemented?
