Champion Dynamics I want to see in the future

As a 2-year player of League of Legends, I feel happy to see such a diverse array of champions, most of which come with very diverse mechanics and each providing meaningful strengths to a team composition, with that being said, there are still a lot of things that could be added to create an even more vibrant pool of champions, here is just a few of them:

1. The dearly-missed clothesline mechanic: Some older players may remember that Karma could tether to an ally, said tether could then be used to damage an enemy by making them pass through the tether, I actually never got the chance to use this because I started playing in 3.5 which was when Karma got reworked, but needless to say, it looked really fun.

2. An ACTUAL tag team: As an avid wrestling fan, I've always wanted to see a Yordle Tag Team on the rift, pretty much 2 champions in 1, both complete with different abilities and stats, and the ability to tag out at will (long-ish CD scaling down with level and disabled if one of them dies, they grant 50% gold and have low stats, cos balance) and an ult that actually lets us use them both at once like shaco's ult, they get double team moves and you have to kill both of them.

3. Tactical Insertion: No, I'm being serious, Tactical Insertion would be a pretty fun mechanic in this game, being able to choose where to respawn would be pretty badass, of course on a long cooldown so if you choose to use it, then youd better find a good place to use it, they can also be destroyed by enemies (requires a 7 second channel to do so and can be interrupted by taking champion damage) and is 1-use, also lowers your respawn time to 10 seconds.

4. A parasite mechanic: Essentially the ability to hide in a target unit and then reactivate to leap out to create a surprise 2v1 assault, maybe something for the enemy's buff bar so noobs dont qq about how broken it is. It would be quite a fun concept for a jungle champion.

5. Ability to mutate and control minions: Well, Urgot's rework is coming out soon, the ability to mutate and infect an allied minion's brain and take control of it would be quite funny, as a champion, wouldnt it be hilarious to die to a minion? Even if it is hideously mutated? I'd like to see a different champion who can control a minion and either split push or take care of a greedy guy who thinks they can try and waveclear after barely coming out on top of a gritty trade, and plus, wouldn't it be fun to control a minion for once?

Does anyone else have some interesting Champion dynamics they would like to see in the future? If so, share them!!!
