Vampires have been Tier 1 for quite a while now so they're either due to be power creeped or nerfed. I'd personally wait until the next main box but that's just my opinion.
Powercreep is never good and will never be good for the game. Do you want DL to share the same fate as the tcg where duels only last in 1 turn and only decided whether you/your opponent have handtraps or not?
