About "One Skin" patches....

( Sorry for bad English, this is not my native language ) Recently "One Skin" patches became very frequent. ( Cemtech Trynda, Pulsefire Cait, God Fist Leesin...Festival Anivia....Elementalist Lux...) I understand that making a good skin takes time, but what about the 750RP skins? Do you remember them? https://www.youtube.com/watch?v=D3C6Gr56xko 4 cheap skins at the same time that ACTUALLY LOOK VERY GOOD! Just like the Academy ones! These became very rare... I understand that 520 RP skins won't come back but please don't kill 750 RP skins. They look really good. There are a lot of people like me who can only afford these skins. Please don't forget about us....
