The best thing they could’ve done for eclipse Leona...
Implement a day- night system. To start things off, I personally think that they should’ve held off the skin until VS 2018 with Diana (and Leona doesn’t have anything to do with lunar and moon) but I also think that that making Leona mains buy two skins that will cost 3k rp in total is a bit too much. What they really could’ve done to make things super interesting is a day night system. Depending on your region/server, the skin would be in sun/solar form during 6AM to 6PM, and lunar/moon form during 6PM to 6AM. This would really add an interesting aspect to the game that Riot has really never touched.
