@Riot Please Consider Leaverbuster's Omnipresence
Is it really necessary that leaverbuster completely lock you out of your client for the duration..??
Would it not make more sense that this extra long queue time could be used to browse the client and not feel punished like a small child? You are locked, barred, preventing from interacting with the store or champion pages or runes or masteries for, up to, 20 or whatever minutes.
This seems like too strong of a negative reinforcement; you already took away access to normal queues, do you really need to remove our interactions completely for the time being?
Because honestly, after 20 minutes of waiting, I feel panicked and rushed to quickly change whatever rune or mastery pages I thought about in that time.
Please, I urge you to reconsider your punishment systems and the subtleties in them. I'm glad chat bans now tell you WHY you were banned; please look into this other punishment now too.
