No, it's fine.
What we really need is the same amount of cards per element now. There are still elements with 13 bazaar cards while others have 16. Do not forget fire and aether, they don't have an extra rare like water and time. (The latter actually have 14 bazaar + 1 = 15 cards)
All in all, we need some 17 new cards to put the elements on par with death, but 15 cards per element would be an improvement also.
