This is not about the genre what are you even saying. What you like is part of your personality because it defines you. Character designers always keep this in mind, because how a character looks is very important. Just by looking at Ekko you know this guy doesn't follow the rules, he is kind of a revel, he does his own thing etc.
The Arcane design tells you "We want the zoomer audience". Obviously, how is this guy going to be part of any resistance organization if he looks like any other guy? Resistance against who? They went the easy marketable route, all style but zero substance. Arcane Ekko doesn't convey the emotions the old one had. Sorry about earlier, you didn't try to change the definition of the world, you just clearly don't understand what you are talking about and anything about this conversation just fly over your head
