Requesting some minor QoL buffs for Warwick

Last night I took warwick's rework for a few test matches against bots to see how it felt, and I have to say, it feels awesome! Balance aside (whether he's OP or UP is irrelevant to this post), there were two things that bugged me about him, both having to do with his W blood trails.

First is that it feels like there is too small of a margin of error when following the trails. If I strayed about two teemos to one side or the other while chasing an enemy, it had a tendency to lose the trail, immediately dropping my speed even when pathing directly towards them. Making that margin of error a little more forgiving would help a lot.

Second is that sometimes the trail vfx were kind of hard to see, upping the saturation slightly would help, and possibly sharpening the edges slightly to increase clarity. However, this wouldn't be an issue if the trails were a little more forgiving.

Overall really happy with how he turned out!
