How the scaling works in this game?
Like why you guys are fighting against level 400 heroes?
they keep tweaking it but in general scaling works something like this.
you have a background win loss counter that effects your overall rating (getting attacked in pvp counts as a loss)
there is also something tracking what enemies you are taking down and how long you are taking to take them down. Thus if you are using spiderman to beat up level 230s repeatedly then you are more likely to face level 230s.
finally each node in an event has it's own stupid counter... basically the more people that play a given node in an event the harder it gets overall... so usually the more you wait to join an event the harder it will be period.
oddly enough, as far as I have read, your actual roster doesn't effect your rating at all.... so if you were to sell your roster off for the sake of restarting with a challenge you would still have to deal with high level enemies as if you had your original roster
