How much would it cost to rank up from Bronze 3 Promos to Silver 5?
provide me more info on your region,how much do LP do you win/lose That I'm not sure of since I haven't played in awhile. I would assume around mid 10-20. I play on the NA server.
if you win less then 16 and lose more then price will be higher becuse i will first need to fix your MMR
