Bank?

I was just thinking that some people find it unethical to buy new/current champions with** RP** and put in the work to get them the long way,** IP**. A thought had occurred to me that what if** RIOT** implemented a banking system to the game so you could store IP as a "rainy day fund"

EX: New champ comes out and you just spent all your IP that you spent HOURS getting. but no worries you saved enough IP to buy a new champ because you put your **IP **in the Bank.

Its rainy day money essentially, put aside what you need until you need it.
