@Riot Vlad has a 44% win rate and it will only drop.
Ever since his rework came out I felt like he can't be balanced with that kit, and nerfs confirm that. He got nerfed like 5 times in a row and even before he had like a 45% win rate. In LCS he might work since all they do is farm for 20 mins, but in solo q you don't have 20 mins to carry yourself and your team doesn't have 20 mins to wait for you to become relevant.
If you buff him, they're just gonna keep going SV build and be toxic to play against, if you nerf him some more, he's gonna be unplayable, thus he needs another rework. I feel like you need to balance out his Q, because first Q being garbage and then crimson rush Q being broken is not a good idea. Also, hp scaling on his E is one of the things why he's so toxic to play against. And to play as, at least for me, still not used to not hitting everything and not being able to wave clear like a beast before. If the problem on his ult is his dmg amp, then you can switch it to something like brand ult but with an infection that spreads to player to player and only increase dmg on that player while he has the infection or something like that. Also, blood lord skin was WAAAAAY more badass before and his animations were WAAAAAY bigger and cooler than right now.
