Thematically unsatisfying champions
Let's take a look at some champs. First, some that actually have good kit to fit their theme.
Based around turning back time. Ult turns back time. Checks out.
War horse. Gets damage from speed, as if he were charging. Has 2 abilities which allow him to "charge" into battle. Checks out.
Lone ronin who spends his life fighting and fleeing, in search of his master's true killer. Has lots of mobility and is literally rewarded for walking (flow). Checks out.
Hemomancer (blood mage). All abilities have to do with blood and HP. Checks out.
Evolving predator who gains power as he kills. Gets evolutions as he levels up. Checks out.
Those are just a few examples of thematically satisfying champions. Now let's look at the other side of the spectrum.
Badass chain guy. In the past life was the warden of a prison, notorious for torturing inmates with chains. He was to be feared by all. Is a support who's most noticeable feature is saving an ally with his lantern. Practically the opposite of his theme.
Fearsome predator who can transform into a cougar to stalk her prey. Plays like a weenie all game chunking with spears then running away in cougar form. At least her rework kinda fixed that. Kinda...
God of war known to be able to inspire men and give them the strength of 10 men. Known to turn the tides of war and shaped history itself with his influence. Has almost no impact on a fight. Doesn't buff allies at all. Is a mediocre fighter.
Blind monk. Player still has vision when playing him. 0/10, good job Rito. (Jokes)
Ninja. Literally a ninja. HIS LORE LITERALLY SAYS HE IS A NINJA. Builds full tank, does almost no damage. Has no real reason to build damage. Scales off hp. Ninja
Protector of the cosmos. Dicks around all game and screws you with ult. Alright, this one is fine, because technically he does make sense thematically, but it depends if the person playing him knows what they're doing and isn't a dick.
