Big mistake ! rentals

Can you see Chao's gold rental? would be divided by 4
chao gold epic = 2500 => U gold epic 10000
so the rent must be at least divided by 4? if chao gold ?? YES
but at game is there are doing the price of the extremely horrible for people who don't know? price is the same same? compared with the money off? here is the proof

gold legendary :) chao 17$ 12500 P -> gold legendaryu U 21$ 50000 P ??? you are buying an item that is worth 4 times its actual value! với 17$ ! = 3 gold epic U => 30000 P

Many people will hate me for posting this but look back? Should you spend money to rent and do such prices?
Rare and Common ???
............... ? X4 money ?
and surely you will also know that the price is very cheap compared to the price of other cards!!!! Be careful when renting last day! Don't lose money when you're not paying attention! good luck ! and open the box to gold legendary !!
Thank you for reading....!
