The current exploit of maxing just one or two splinters with the lowest cost cards to get easy wins over evenly assembled lower level decks takes much of the fun out of the game. No one enjoys getting thumped indiscriminately by higher level cards.
How about you petition the SPL team to only allow bronze level cards to be played while in bronze and allow players to stay at the level their cards are suited and progress to the next level when they are ready and at their own pace. Then a whole bunch of players will go back to modern and the game would be so much more enjoyable to play.
