T14 give better loot then T15 or +

Posting this in bugs because it is,
played around 30 juiced up maps +towers from T14 to T16/T17
drop rates for tier 3-5 items in T14 is 50% higher then T15 or more
Orb drops is insane in T14 and garbage in T15 or more ( exalted, alchemy even Divine )
you guys should seriously look into it
