Will there be anymore skins you have to buy with gemstones?

Hextech crafting has been out for less than a year (I think) and there is already 2. So there is likely to be more? Not sure, since the general consent is ppl do not like hextech crafting and feel like its a waste of RP, so making more exlusive skin for crafting might induce more hate OR it might make it more of an attractive alternative. Not sure which is the case.

So long as Riot is making money off them or believes they can, they will continue making skins until they don't make money anymore
