Hear me out: Dragon trainer Taric.
His W gems that float around people are baby dragons.
His E has one breathe a gout of flame.
None of his skins are fire themed either, and who wouldn't want to gift baby dragons to allies?
I could see Taric being a sympathetic slayer of dragons.
He feels bad for them, and if he were in another place he would not kill them, but is forced to.
Nah, Taric stopped a war to save a flower. There's no way he'd kill dragons. Another dragon themed skin would be cool, but not a dragon slayer.
That's really neat but Dragon Trainer is more his style, character and lorewise.
