It's 2015 and Riot still didn't fix the size of its champions
http://4.bp.blogspot.com/-hClJZIy1e_o/VE8tvECHpOI/AAAAAAAAbn0/arQAJ1w0mLE/s1600/naatt.jpg Dear Riot, sometime ago you reworked the good old Sion. He is really awsome now and JEEEZUS IS HE BIG. I belive he is the biggest tank around (exept maybe zac full Hp or Cho Gath 6 staks lvl 16) but this is a good thing. He is really intimidating and a colossus as he should be.
That would be fine if the other champs that should be big if not BIGGER then him are just tiny in comparison.
One above the other is Nautilus 
- Man he should be a titan of the depths, something incredibly big and powerful, and he is much smaller then Sion. In the cinematic he is freaking GIGANTiC.
There are others who should be bigger of course. Like ZIlean is abysmally small for being a male character.
In general, i feel like tanks should be on the same size as Sion more or less, and some other champions need some scaling up or down. It's a matter of consistency riot.
Also why this wasn't already done? i mean it should be a pretty quick work to scale up or down some models.
LIST OF CHAMPION THAT NEED SCALING (tell me if i miss someone and i will add it)
• 
Malphite need a BIG scale UP in size. as you see in his splash art and general theme, he should be probably the biggest champion in league. Put him on sion size at least
• 
Shyvana Dragon form should be a bit more bigger. ITS A FREAKING DRAGON RIOT
• 
Zilean is so damn tiny for whatever reason. Fix him up please.
• 
Should probably be little bit bigger
• 
Too tiny
• Same case as Malphite shouls be Big as sion if not bigger
• 
At the start of the game he is so tiny... Fix him pls
• 
Still too small
• 
Too small for no reason. Really small
• 
Same as Kayle. No reason
• 
without his mecha-suit he is abismally small. Fix pls
Dont even get me started..
Very Large Size
12'1"-25'0"
Slightly below Titanic, these guys are still huge, but not quite "Attack on Titan" killer huge. No human and most other animals could possibly be this big without serious biological work or being very old/prehistoric since all things back in the day were typically very big. They could also be increased in size due to what they are wearing in Nautilus' case, although Im pretty sure he was modified to some extent since he is larger than an anchor.
(Mega) 
(during ultimate) 
(during ultimate) 
Above Average
6'3"-7'5"
These will typically be humans that are slightly taller. These begin to get more realistic, real life sizes. Most will be warriors here, with the rest usually being empowered humans by some sort of power, for example. A special note on Azir to say that he is only a newborn as far as Ascended beings go and I don't think Xerath is fully ascended since he kind of got into Azir's ascension process halfway through, probably not getting the full package. Plus, Xerath is confined by his coffin prison.
(Spider Form) 
(Bird Form) 
Average
5'1"-6'2"
Your day to day normally sized champions. Not too tall and dont need to be.
Small
2'0"-5'0"
These are where small animals and yordles usually come into the mix. Almost no humans are here, basically only children.
Very Small
1'0"-1'11"
These are the smallest champions in the game. They are either very young already small creatures or have said to be extremely small for their kind. I debated putting Veigar here, but I don't think he is this small even if he is the Tiny Master of Evil.
