Modern Nerfs

Give Annie a Veigar nerf. Viegar got nerfed by removing the instantaneous activation of his Event Horizon and made one of his abilities a skill-shot. It's too easy for Annie to seize an opportunity with the area of effect of her ultimate to stun people, it needs to have a delay. People said "no one will play Viegar ever again," and they're right because he gets banned because of how OP he still is. In fact, I thought I saw him banned in LCS recently.
And, since Annie already has CC to match up against people like Lablanc or Yasuo, it wouldn't be a terrible idea to make Disintegrate into a skill-shot just to give her some more finesse instead of mindless auto-targeting.

Another thing is just as with Reksai, knockups should be proximety based. The closer someone is, the more they get knocked up. The further someone is, the less they get knocked up. This would particularly effect Zac and Wukong. Whoever Wukong or Zac directly dive will get knocked up the most, other enemies will only get knocked up a small amount. It's already enough that you can dive whoever you want, but the entire enemy team shouldn't be destroyed by one mere attack. Imagine if Braum could apply all 4 stacks of Concussive Blows to all 5 enemies in only 5 seconds, you'd either hate it or pick Braum every time.
