It’s just stupid. I wasted ALL of my power ups while using a Mythical Bro-mon and still lost. I wasn’t doing a boss, I was just battling a Mythical Bro-mon (Actually it was the OG Bro-mon), and for some reason the wheel spun and landed on fearful. I used everything in my backpack but there was no point. I couldn’t land a single hit. NoT oNe!!! I think this modifier should be nerfed. A few ways I think someone could go about that is by removing that from the wheel when versing an epic / fealmonew-mythic (wth autocorrect. I typed legendary-mythic and it autocorrected to that. 
WHATTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT) anyway, when versing an epic / legendary – mythic, I think that modifier should be off the wheel. Another way (which I’d prefer more) is if you are battling a mythic, (or a bro-mon above the rarity of the bro-mon you are using for the battle) it shouldn’t be possible to get the wheel. The last way I thought of to nerf the fearful modifier is reducing the damage the bro-mon that you’re battling deals or increasing the damage that you deal. DANG this got long FAST!!! bye
One time I lost to a common bro-mon using a mythic because of this mod :/
I agree your absolutely right
Not for me! It rarely ever scares my bromon. 
@sweezy you should keep this in mind
