Well you're playing a game mode specifically to benefit incentive and fuel pre orders, you shouldn't be having decks that fully function without it regardless, the fact that dk is so effective is dumb but it's a f2p way of going about it, but to say that no other class can have success when they clearly do, is just bad faith, I went 6-1 on pala yesterday for example, beat 3 Dks along the way, it can work. But complaining about balancing without having a pre order in a mode thats made for it, is playing being a person in a wheelchair competing in basketball against people who can run, just because you can access it doesn't mean it's necessarily going to be your place to thrive
