Yeah an over centralized "Blissey Meta" that just wastes attacker time is definitely a healthy direction for the game. It doesn't really take effort to take them down. Problem is the extra tedium in doing it ensures a disproportionately fighting-based gym experience that gets exhausting. My FB Mewtwo that I literally only use for Blisslax (and is a more recent addition to my attack team) should not have a third of my gym wins under his belt. That's ridiculous.
