Riot, I hope you are Prepared for the shitstorm you've made.
First there is the current issue with balance, that is cool to an extent. Balancing can go up or down and too bad it's down at the moment.
But when you start to fuck with promises that people are getting refunded for their IP and only give people 100 to 300 b. essence instead of giving them a refund for the runes they've spent tons of IP on. I am sorry but you fuck'd yourselves over and unless you fix this shit, you are gonna lose respect and players. Fast.
