They talk of playing Aphelios as something that would require a lot of knowledge in knowing what your strengths are at every moment, depending on main and off weapons. But isn't that also true for your opponents? And it's even less clear to them because you can't see what his off hand is like the player can. If the different weapons are as "op in certain situations" as described, I can see some hesitation or frustration being caused by not knowing if he can swap to a weapon that will negate what you want to do against him. Probably less so for his lane opponents because they will presumably see both weapons and new ones when they come out. But still, I can definitely just hear a lot of people going "wait wtf, he can do that" for much longer than other champs. I'm buying him day one
There's really only one weapon that requires enemies to be aware and that's Gravitum, the big black hole looking weapon.
A huge art of Kindlejack's work was making sure everyone could tell which weapons Aphelios was wielding and to make the way he held them seem clear.
