She needs her size reduced badly. No champion in the game suffers from unit collision issues even half as bad as Leona does, and she isn't nearly solid enough of a champion to justify this enormous handicap.
I regularly get stuck inside of minions in EVERY Leona game I play. Probably 50% of my deaths as Leona could have been avoided if her unit collision wasn't so bad.
Hotarµ2 votesMinion block is a large problem across the board and should probably be removed (IMO). It isn't restricted to Leona.
However, if you died due to minion block, there's a 99% chance you were going to die anyway.
The thigh guy1 votesWelcome to kayn main life. His size is SOOOOO much larger than it should be. It’s bad. He gets stuck on everything, and it can cause him to auto die on his chicken clear now.

People say Skins don't effect champion size, but I challenge them to play those Ecplise skins, and see first hand how pay to lose those skins are.
Alzon1 votesIt’s primarily a latency issue. I mostly play big beefy bois and very rarely have problems with minion block. Even late game 
and dragon form 
have minimal issues pathing around minions.
PhearBunny1 votesLeona is the same size as a full size Cho'gath. Which is completely unreasonable.
