Solar/Lunar eclipse skins make Leona unplayable.
Why?
First of all, Leona isn't a good champion to begin with.
#1 it effectively doubles her screen size. which drastically slows her movements and telegraphs her movements even moreso, this is a problem because Zenith blade is already tied as the most telegraphed, predictable, and avoidable skill shot in the entire game. This skin exaggerates the problem. #2 her auto attack animations are just awful. Shes too big for where her autoattacks are hitting, it looks ridiculous, and it makes for awkward combat. #3 shes already slow moving. Making her the size of max stacks chogath makes you feel like youre playing as a giant snail.
Its a pay to lose skin. Much like Project Vayne.
