I just find this very worrying in my honest opinion. I really don't want them to be constantly pumping out as many EX boxes as they have lately. There is too much product out there that has at least 5 or more Booster Packs, making the pricing insanely unwelcoming for new players or those on a lower budget. There could be decks seeing much more play if it weren't for the money barrier.
Otherwise, I really hope this set does well with it's rarities, I don't want BREAK cards to be too hard to find... lol.
I think Break cards are the same rarity as EXs.
But yes we are as it stands overloaded with EXs that aren't seeing sets yet.
