personally if I had to price these skins for RP, they would be for the most part (except this one) the epic skins costing 3250 rp. these hextech skins are amazing, but the chances of getting a gemstone are sometimes so astronomically low people sometimes forget these hextech skins even exist. I have 4 gemstones, meaning I am a luck SoaB, but i'd rather pay cash for a guarantee than spend nothing on a gamble. RIOT, if you are listening, after 6 months of a hextech skin's life, release it to the store. You are going to make money and satisfy a large portion of community. People didn't like when you re-released Championship Riven, but it allowed a new batch of players use a classic skin. Another suggestion, is have 5 hextech skins in rotation, and when the 6th rolls in, knock the first onto the store.
I hope anyone reading this understands im not vitriolic or spiteful, I just want to enjoy this game to most of my ability (even when my adc is a complete shitlord and leaves me [the support] in the wind.)
