Ideas for reworking Warwick's Kit

Now that Taric got his much needed rework, it is time for us to consider what champions desperately need one. Warwick is one of my personal favorite champions but because of his lack of team fighting capabilities he can be very frustrating to play in the late game, and his design is in desperate need of an update. Personally I think in order to keep Warwicks kit mostly the same but give him some late game potential here is what I think should happen. His passive needs no updates, its great as his. Make his Q an aoe cone that does reduced damage to enemy minions but Warwick does full damage and life steal against enemy monsters and champions. This would give Warwick some decent team fighting capability as he would now be able to finally hit more than one opponent. With his W make it so that while its active Warwick can put an extra stack of his passive on his opponent. But he'd only be able to put 3 extra stacks on his opponent once his W is maxed out. This would make Warwick a much bigger threat 1v1 and would allow him to quickly finish off opponents so he can move on to the next one. With blood sent it should reveal stealthed enemies if they are below half health, that way Teemo's cant use their passive to escape the blood hunter and Rengar can't use thrill of the hunt to get away. I also think blood scent should allow Warwick to deal 25% bonus damage per hit to below half health opponents, and give Warwick more of a speed boost per opponent scented. With Warwick's Ult I think he if Warwick uses his ult and the person Warwick uses it on dies during or soon after the ult is finished Warwick can reactivate his ult to lunge to the nearest opponent, for half the mana cost of the initial lunge. Warwick can do this up to two times. If no opponent is in range or you don't reactivate the ult the cool down is halved. This would give Warwick some much needed team fighting ability and would still force a summoner to decide whether or not its worth the mana to execute. Tell me what you think about this idea in the comments, and upvote it if you think this is a needed thing for riot to do.
