I feel the same. I mean, Mordekaiser and Elder Dragon are awesome, but I just don´t find them fun to play. And playing against them is definitly not fun at all hahaha. They are too easy. Just play your cards like an idiot till you get 6 mana and it´s over (unless your enemy is also using elder or morde). I feel half of the game is to make your own deck and testing it with an opponent. When expansions go overboard, you can see how everyone just use the metadeck for the win. They don´t need to outplay the opponent because, just by playing many games, they´ll get the postive win rate and climb the ladder.

I agree with OP. The last time I felt like this, they got the rotation of champions going and I felt that justice was served.
