If everything's broken, nothing is broken.
That's one balancing philosophy. Elements, however, does not use it, and should not use it. It's high time shards were moved into specific elements. That IS the name of the game, not 'Shards' or 'Other'.
And indeed they have. Still, now we get complaints they don't work as well as before in duos/rainbows/whatever. Ya can't please everybody. I however am glad they are now specific.
@BluePriest I agree. No variety is a bad thing.
I think I've got another insight. Perhaps the troubles people have with their deck is their playstyle. Sometimes, there are mismatches, so they can't perform as well as they're designed.
My choice of play is jack of all trades. If one strategy is stopped, I use another. If I used a pure rush deck, Dimensional Shield would kick my ass. With "joat", I can adapt.
