First time posting here, so sorry any mistake ^^!
Well, I'm surprised with all these runes. You did a great job at it. I'll test a bit more, but I'm really happy with the results. But I wanted to talk about the loading screen and its components:
* The loading percentage I think is too small and could be a little bigger, the definition is too low;
* Maybe You could get smaller sorceries icons in order to increase the rune icon size, or a smaller summoner icon.
That's all for now, I'm new at PBE and I was really excited to give some contribution.
Thanks for the oportunity to join PBE!
