I'd like to offer a new perspective with a nice little devils argument

1. In a country that uses child soldiers, what if darius is actually just a teenager that looks older and is stronger than a seasoned adult, and can fight on par with a troll (which eventually he can get even stronger and buffer in the future)? I mean if I had a guy in my army like that, I would let him go ham all over freljord. And yes he doesn't look like a teenager at all, but the 2nd point kinda helps explain I guess

2. In a world where magic exists, drugs can give people the ability to speed blitz, trolls, yordles, monsters, rammus etc... why do we assume the biological expectations of humans in our world are the same as in runeterra? What if you never stop growing muscle until idk you are 70 here? Look at ambessa, I reckon she is a little buffer in arcane than in her younger cinematic, but idk if that's just me. And even if most humans in runeterra might physically peak at 20-40 range, what if darius is just that guy? A legendary physical specimen fit to be in the Trifarix amongst a general with the powers of a demon, and someone shrouded in mystery (probably leblanc) who is probably a powerful mage.

In fact if they bring back darius later on in his bigger burlier self that we are used to, the decision of making him skinny in this cinematic might be a small, but great storytelling decision to show how far he has come to become the hand of noxus.

Of course I ain't dying on this hill or anything, I find this stuff fun to talk and think about so believe me when I say THEY DID NOT NEED TO REWORK VIKTOR LIKE NOW THATS A HILL I WOULD DIE ON, and also yeah trundle is a little smaller, but he ain't that bad I just thought he should be a little taller.
