It would be better for riot to stick to amking themed champions than gameplay champions.
The recent Pantheon rework is the inspiration for this.
His new rework doesnt add anything new gameplay wise. What it does is embolden that one man army, for honor and glory, balls to the way, and testosterone pumped theme that many think of when they think of a spartan warrior. Besides pantheon riot seem to be chasing after the interesting gameplay champions more versus the thematically refreshing champions and I think thats the wrong approach right now. there are many champions with cool gameplay ideas but the ones that see the most play are the ones that also have the cool theme attached to them: lux, yasuo, akali, zed, and ekko. You really cannot go wrong with a wind samurai, hipster ninja, shadow assassin, and time assassin. These are interesting and cool champions that have gameplays that satisfy their themes. Cool mechanics aren't enough, insert qiyana, skarner, yuumi, etc.
Recently, Riot has been making champs and reworks with cool mechanics but themes that arent properly explored. My examples would be Asol and the galio rework. Asol is a space dragon...enough said. They could have built on the space dragon theme in a much more direct way but they went for an interesting gameplay choice that isnt that refreshing to play when you think of space dragon. Galio is another one that fits this category with his rework. I honeslty played old galio a lot and liked his old kit much more because, even as clunky as it was, it fit his theme much better. I honestly am not sure what galio is supposed to be right now. Is he a tanky mage or a tank or just a mage that can go tanky...
All in all, I think Riot should focus on more directly themes that everyone would love to play and let the gameplay flow from that. I would love to see another knight like character in the style of garen, darius, and morde but he focuses on ccing the enemy more than doing damage. themes like that are brushed to the waist side because they have been done before and are too simple, but I think thats what league needs rn.
rework. The Fire-Fury-Dragborn fantasy should be way more fun to play, but her kit just isn't that satisfying.
One of the ancient darkin is more fragile than fucking Ezreal and needs to be babysat by his team to not feed.
