This rant smacks of incredibly new player. If you think Mar'dred is the best card in the game, I'd be surprised if you've played for longer than two weeks. The game has a lot of problems (hint: the largest is declining playerbase). Arguably the second problem is either wildcards or seasonal cards being wildly unbalanced. Glory continues to be very useful for guild conquest, even if you've finished the battle pass. Underperforming cards, while regrettable, is a much smaller problem than overperforming cards (which they've been doing better on lately). I don't think changes to a single thing you've complained about would have a meaningful impact on the game.
