The thing is if Foe is clearly #1 like people here are saying/complaining about then nobody risks losing anything when they prep them or duke it out with them in the wilderness against them.
If Foe win as people would more or less expect, the reaction would be along the lines of "oh yay they won again what's new we weren't expected to win, blah blah."
However, if the underdog wins then it becomes a good motivator to continue going at it and possibly dethrone. Even if Foe are overpowered, there's always a chance at winning yo.
Honestly Foe have more to lose by giving fights to everyone yet they don't seem to be afraid and actually are willing. Even if it means teaming up on the weekends to match their pull lol, then go ahead and do it. Make some huge ass clusters.
