To be fair, Mr. Rogers Yellow was the alliance rewards for TBTI. Also, the structure of the Heroic event really made things awkward: each mode and each round needed to have identical placement rewards, else it’d be “unfair” to those in differing time zones and with different roster strengths.
I agree that Hulk K should’ve been swapped out of alliance rewards in the last PvP, but I think future Mr. Rogers cover rewards will see healthy rotation.
The Dark Avengers tournament should have had red (or maybe yellow) as the Alliance award. There was really no reason to have blue be the alliance award there too.
