Because Summoners Rift looks like a Toy Story with different toy soldiers. If I'm being correct, Sona's height was adjusted when she has received new textures. It just hurts me to realise that Vladimir's Soulstealer is much taller than his legendary skin Blood Lord.
It bothers me an inordinate amount that Sion is quite a bit larger than Nautilus.
Yeah,I think alistar and Maokai could have become bigger with their updates too.(I think they became a bit bigger,but simply not by much)
needs to be bigger
Or Tristana being the height of many human models but having a quarter more overall mass?
One of the Riot members said back when Sion came out that because of his huge size they would end up resizing some. Said increase Nautilus by 10% or something.
Because Blood Lord is a pretty old skin, and that Soulstealer is one of the newest ones.
Come on, I don't have to bring up about Final Boss and all of Veigar's other skins, right? Just look at his head, and compare it with mines ingame and we'll know.
But yes, a LOT of the ingame models are in a DIRE need of resizing...
Major need of high change:
Yeah, also did you notice that Gnar is somehow bigger than Ashe and many others when yordles are very small, it makes trying to figure out their relative size compared to others reallly difficult.
updates
Annie is a giant... just look at her head size.
Malphite and Nautilus need it badly. They look puny to Sion and that's a little odd.
I COMPLETELY AGREE. I feel like riot needs to do a massive size change. Make some of the big men and tanks larger and just make them have more presence.
