a bronze player finally getting to gold is a bigger improvement than a gold player finally getting
to diamond.
bronze covers 0 MMR to 1100 MMR.
gold to diamond covers like 1500 to 2400 MMR
this is funny because of a few reasons.
first is because if i asked you to tell me who improved most in this game, a b5 that got to gold 1 or a gold 5 that got to diamond 1 the answer would likely be the second, when in fact its the first.
the other reason is because bronze is so spread out that you can carve it into 3 distinct tiers by itself. which makes a terrible experience for bronzies.
