理由
Olaf is hard for Diana because he contradicts your fight plan: you want to group, pull, burst, then reset off the chaos your ultimate creates. Olaf wants a simple, long fight where he runs straight and wins through duration. His ultimate removes a big part of your entry control: your pull doesn’t stop his trajectory, and you often have to endure him rather than orchestrate the fight.
レーン戦への影響
In the jungle, Olaf punishes bad stances: scuttle contests, river entry without vision, or a gank that turns into an extended 2v2. If the fight drags, he takes over and forces you out, costing objective timings. Midgame, when you engage, he can ignore front-to-back and chase you or your carry, making your engages far less clean.
立ち回り方
Positioning and reads: avoid flat river fights when you don’t have an angle, because that’s where he runs you down. Key timing: play around his ultimate—if he burns it on a small exchange, you get a real window for the next fight. Concrete decision: if Olaf is on an objective and you can’t burst him with your team, choose cross-map (Herald for Dragon, tower for camps) instead of committing into the extended fight he wants.
