WW is great for creating map pressure early to mid game. WW late game doesn't scale as well as hyper carries & cannot one-shot enemies like assassins.

Ideally, you should be looking for succesful level 3 ganks, personally, I think full clears & tempo are OP. Use dead-time after scuttle-crab to go for ganks on mid/bot. If mid or bot has lane priority look for an early dragon. If not, full clear, place a ward & play for void-grubs.

At level 6 WW should win most 1v1s. WW - Q is best used after taking light DMG. Holding WW - Q at the right time will follow flashes/dashes, utilise when enemy tries to escape (beware of over-extending). WW - W before ganking or entering teamfights/objectives for added movespeed & vision on enemy. Use WW - E when engaging enemy for the DMG reduction & let it realease on its own, unless they attempt to run/space. Utilise WW - R when you are low/mid health, beware of overextending if chasing or wasting R on a full health tank.

WW's kit loves attack DMG & attack speed, he really feels canon when playing with DPS & resitances instead of full tank. WW cannot critical strike so don't attempt to build any. Build boots after 2nd item.

WW teamfight potential is low unless you've gone a tank build and willing to be the peel bruiser. Instead, look to pick enemies off that are over-extending their side-lanning or pick off the squishy backline to turn teamfights into a 4v5. Don't let enemies move by hitting them with:
W - R - E - Q (hold) - E release.

Punish low-health enemies that make the mistake of not recalling.
