Warwick Top has always been one of my pocket picks since the rework. I was a Riven OTP and enjoyed playing Warwick jungle. Then I took him top lane by accident and found that I very did well. So in season 7 I had over 140 games of Warwick top and had a 62% winrate and achieved Gold 1, which was my highest rank then. In season 8 I hit Platinum 4 and Warwick top was my 2nd most played, 35 games, and my 2nd highest winrate, 62% again. Today in season 9, I don't play ranked much anymore, but Warwick top is currently my highest winrate, 83%, but I have only played 6 games with him and I am currently Gold 2. So I find warwick top to be very effective in low elo to mid elo (plat). I am not sure how well he will fare in high elo.

Warwick does a lot of damage, especially with Sheen. Many opponents won't expect this damage, so use this to your advantage. Warwick's Q, if held, nullifies almost ALL CC's, except: Stuns, Silences and Suppresses. So a well timed Q-hold can counter all champions who rely on snares or dashes. You're only enemy is grievous wounds.

You typically want to trade using your Q, but be weary. Your Q mana cost is extremely high. When trading, you want to Q in and then use your E to reduce damage from your enemy. While your E is active, auto attack them and Q them. If your E is about to run out disengage with the fear. Only use your ult to prevent your enemy from escaping, if you're low, to finish them off, or to escape.

With Tri-Force and Hydra built, you can chunk squishies. In teamfights, play as the front-line and focus the squishes as you can tank with your E and heal from Ult and Q. Use your R to engage into fights or to catch out enemies. Make sure to E before ulting into a teamfight as your E autmatically fears when you land your Ult.
