In game shop

Hello my name is Ben and I have a pitch. Everyone always struggles for which champion they want to buy, what suits them best. And this is a major struggle that i have always had is at first i may like a champion but then i realize they don't suit me, so then I get a refund. But the problem with this whole process is that we are easily running out of refunds. So my idea is that you should be able to test any champion you want before you buy them. This does not mean they can play that champion with other players just in a 1v1 custom against a bot. Players will no receive influence points or experience on that champion it is only a way to see if that champion is fit for your skills. I know i am no challenger but we all have ideas so this is me a humble Summoner asking for ways to improve a great game that i enjoy asking for a change to make this game even more compatible to its users.

Thanks, 76543az
