Leona Changes.
I think that it's time for Leona to be changed around a small amount. I feel as though Leona should have the rammus treatment where when she pulls up her shield she slows down by 35%. She would then gain a little more armor but the range of her W's active would be increased drastically.
Her Q would then be changed to apply 1 stack of Incandescence. She would gain the 225 range for her Q and apply the stun.
Incandescence would be her priority from her abilities. She would want to keep this constantly up on priority targets to allow her team to burst.
(I think that her passive could be changed as well to scale off Leona's total armor [or bonus] that scales with level. For instance it currently does 20 magic damage at rank 1. If it would be changed to deal 65% of Leona's armor, she would scale a little better but still be balanced enough to have no escapes and a weak mid-game.)
