Revert the swain and karthus nerfs?

Swain is just completely useless against competent players right now. If you land a max range snare early game, it literally doesn't give you enough time to follow up with e+q. Not to mention you can walk out of his snare without any shoes. It's hard for a jungler to gank a swain lane since even landing the snare doesn't do much. It doesn't even save you from getting ganked when you land a snare on both players because the duration is pathetic. Not to mention it has ridiculous mana costs with high cooldown which is why you'll never see a swain player use w in lane to try to harass. Did i also mention swain gets dumpstered on early against anybody whos not completely melee? Even mid/late game he gets kited so hard without mobility and no reliable cc. Zhonyas takes forever to get and hexdrinker is such a hard counter to him, he literally doesn't even have enough mana to all in a squishy who rushes this broken item. The only good thing about swain is his targeted burst is high, his overall sustain is high, and he snowballs really hard because of this, but competent players can easily game his cooldowns and choose winning fights because swain has no way to catch or escape his opponents.

Karthus, his jungling got nerfed so hard with the ap jungle item change. It also makes his early game ganks impossible since lvl 1 wall might as well not be a slow. In lane he now gets dumpstered on by everybody and has no way to escape or catch because his wall slow is now a complete joke.

Swain and karthus already have no chance of catching anybody with a dash, and with the cc nerf on their abilities they can't even catch another immobile champion who buys shoes. Their anti-movement abilities already have long cooldowns and high mana costs, yet you nerf those for absolutely no reason.
