Expert take
Thresh is more of a decision-making champion than a pure mechanical champion. Yes, landing hook matters, but the difference between an average Thresh and a very good one mostly appears in the five seconds before the spell: where he hides, who he protects with lantern, which dash he waits for with Flay, and whether his team can truly follow. He is excellent for players who like controlling the invisible rhythm of a game, preparing objectives, and giving their carry unusual aggression windows. He becomes much less interesting if you only want simple frontal engage or a support that forgives bad timing.
