Honestly that number is pointless nowadays. I have friendships powered up far and beyond the enemy power and still cannot pass.
Randall’s refresh has made him a nightmare to deal with unless you have a strong precise or AOE that can hit him quickly. He needs to be pulled from the majority of friend campaigns for the sake of fairness.
Quite frankly, friendship campaigns are generally akin to running into a brick wall over and over until you suddenly have enough power to punch through to the next one. It’s getting really absurd how much power is required to actually clear them successfully with the given heros - in some cases potentially impossible until insane levels of overpowering is reached.
