Do you know what your reward was for supporting Riot? Continued support and development of the game, rather than letting it tank. Oh, and whatever skins, rune pages, etc. it was that you bought with your RP.
Back when you purchased those items with your RP, you must have certainly deemed them worthy of your money at the time of purchase. How come all of a sudden you demand something more than that?
Nobody is entitled to anything that Riot has done for us. This is a fun little cosmetic thing being used as a promotion to get more people to buy RP. And no, you can't criminalize Riot for trying to get people to buy RP, because that's their business model. If people stop buying RP, LoL can no longer continue.
I'm not sure why my previous post was downvoted, as I'm not bashing Riot or anything, just expressing my opinion on the matter. Same with this post. Hope people understand where I'm coming from...
