Use your W Blood Hunt to chase enemies across the map (even invisible enemies are shown!) and use your Smite to slow or deal more damage, depending on what smite you took. Going out of vision (for example, into a bush that's not warded) resets the aggression from the minions. Think about when the next minionwave arrives and don't fight in minionwaves that are too big! Even though you're very strong, 15 minions will do a LOT of damage and the enemy might potentially win the game of a gank like that if he uses the minions well. Maybe you could try to hold Q Jaws of the Beast + fear from Primal Howl to have them back into your teammate, but this most likely wont work that often. Think about what pathing is the best to gank with. Happens when you gank from behind mostly don't let Maokai, Pantheon or Renekton dash to you and escape for free. Don't let the enemy jump on you to escape when you're ganking. Dont walk straight at the enemy! Circle around them so you have more time to autoattack and less to walk! You can try to be creative with your ganking path after a invade. Cover as much terrain as you can before you arrive for the gank. If this is the case you either want to keep farming, invading or gank from a further angle: The problem is, that when he doesn't have it and is pre-6, ganks become a lot harder than expected.

Warwick is a great champion to gank with in the early game due to the passive movement speed he gains from Blood Hunt. It also scales pretty good, but just in a different way than the Lethal Tempo rune. It's only taken in the Toplane since you will be using it a lot there and almost never in the jungle. This is for a more tanky/frontline approach to Warwick.

I wouldn't take this anymore since Lethal Tempo exists.

This rune can be stacked quite quickly if you cancel your basic attack with Q Jaws of the Beast and will give extra AD. I recommend taking this in matchups where you have the ability to stick to people when enemies aren't that mobile. Fully stacked Lethal Tempo gives you so much extra damage. This is an absolutely amazing rune when you are allowed to stack it. Remember that Press the Attack also applies to all your allies, so they get a damage multiplier too. Take this if you are playing vs squishy high damage champions to shut them down quickly in the toplane. It's often the best rune in jungle, mainly because you are playing for picks and not longer fights. He is even played in the higher ranks by some dedicated one-tricks that can carry the game by theirselves on Warwick! You should definitely try to pick Warwick up if you're new to the game since this champion is easy to play but really rewarding to learn and master. Magic resist items like Wit's End are also quite good against Warwick. Hence why items like Executioner's Calling are extremely strong against Warwick. Furthermore, although champions like Katarina do not necessarily counter Warwick, remember that Warwick is way less effective when he can't regain the health he lost in a fight since he is not that tanky at all without all the healing embedded in his kit. Warwick is good vs burst champions since he can time his damage reduction ability to reduce damage taken in a short span of time (burst) and heal the health he lost back with Q Jaws of the Beast. This is also the case if you are playing against ranged champions like Quinn who excel at kiting since you can't stick close to them properly. Since Warwick relies on his basic attacks for most of his damage, any CC abilities used on him heavily reduces his damage output. He does not bring a lot of CC and falls of later in the game, but will definitely allow your team some breathing room in the early game since he can pressure the map (both the enemy jungler and laners) almost on his own. If your team needs some pressure or early-game damage Warwick is definitely the way to go for your teamcomp. There are some things Warwick is good against and few things he's bad against:
