how is it constantly possible to say the vowel distribution is random when they arrive to my rack in pairs

ooiieeaauu
it is destroying my game and grossly unfair

there are 37 vowels to 50 consonents and realistically i get at least 5/6 vowels most racks
in particular iiu in the last 2 racks

this needs to be addressed and made fairer urgently

@lexulous please improve the vowel distribution
im sick of receiving iii u every game and final rack of iiu
make the random distribution random so it doesnt appear to be all to familiar
dont forget 37 vowels to 50 consonents mean that there should be LESS vowels than consonents not the opposite
