i wouldnt put Elise in there. Having a lot of abilities doesnt necessarily mean it's overloaded. Overloaded is when their abilities overcome a huge amount of weaknesses that a champ should have so there's little counterplay
IE Yasuo's weakness would be a non tanky melee. Normally at a deficit against ranged and skillshots to poke, but overcome by windwall and nonstop dashes to gapclose and dodge shots. Normally being non tanky, most melee cant stand their own against bruisers or tanks, but he has natural armor pen and his passive amplifies his lifesteal to huge amounts. Against other high damage carries, he outscales them with 100% crit or outlasts them with double lifesteal. Doesnt leave much counterplay left. He also has an engage/disengage with Q knockup
Camille is the same. Has truedamage, lifesteal, slow, gapcloser, wall hop, stun and makes an impassible zone. AKA can take on anything and anyone
Champs should more be like rock paper scissors where some champs are weak to some and strong over others so a good team comp covers as many weaknesses as possible. You get overloaded shit when you have a shotgun that solo blows away everything in a rock paper scissors game
