I really really REALLY don't like how Riot hasn't specifically said that they will refund everyone's dodge runes if they removed dodge from the game. Even though there has been many, and by many I mean literally every single player who's bought dodge runes, they instead answered the question very vaguely.
4) and a question MANY would love to hear: If you plan remove dodge completely, WILL Riot refund those IP to those with dodge seals and quints?

4) We will be doing something to make this right for players. Details to come, but our plan is specifically about making you guys happy in this regard. "
This is straight off of LeagueCraft.
