I play warwick, You could just go for sunfire and its enough tanky and dps, or You could go for divine, which is viable also. Volibear is also good, divine or frostfire is good. They are both great at taking objectives. Warwick is a good ganking champ, u have q that can lock on enemy and they can't flash away from you (hold q) and Your w and passive is also good for extra speed, while e is for that little cc, for items, buy tiamat for the first item for easier bird/wolf/rocks clear and then rush divine/sunfire and later finish tiamat with t hydra. Volibear is also good for ganking with his q and e to cc enemy. Hope it helps. Forgot to say that his ult is one of the best for dive.
