Core issues within the current game that need to be addressed.
How players feel: The main reason players feel bad about the game is because we feel like we have little control over the whole game. In season 6 junglers would afk farm leaving laners feeling like they had control over their lane. Although not very interactive it is better than junglers being able to camp a lane and not fall behind due to jungle giving catch up experience making farm junglers not get ahead even if the ganking jungler never gets anything. Ganking junglers should be punished for failing a gank. This leaves laners feeling bad since they dont have as much control over the early game it also leaves junglers wanting more because their impact over the game decreases.
Verticle jungle: Verticle jungle is bad for the game because it makes one side of the map not able to play the game leaving them feeling like they have no control while also not allowing the junglers to interact very much with each other. It's basically the same issue as lane swapping back in season 6 i believe.
Scuttle crab: Scuttle crab isn't necessarily bad for the game this issue is it gives too much experience and gold and spawns really early further making junglers feel like they have little control since it gives so much but you need to rely on having good match ups in your lanes and the laners actually winning the lane in order for them to secure the scuttle. Although i think it spawns a bit too early, making it spawn when the jungle camps are respawing around 4min would also be bad since it would incentivise vertical jungling.
Red side jungle: Red side jungle simply gives too much experience and gold compared to blue side allowing junglers to kill 3 camps and scuttle than spam gank until red side respawns while not falling behind. This is bad for lanes since jungle isn't being punished for ganking all the time while also bad for jungle because it reduces interaction between junglers properly pathing and outplaying each other.
Tower plating: Tower plating simply gives too much gold incentivising junglers to gank a lane even more since there is such a big reward for them on top of the fact that they get lane exp. This also makes bot lane snowball out of control way faster than other lanes. Since there are two champions bot lane and the tower doesn't have extra armor to keep lane swaps from happening a winning bot lane gets more plates.
Edit: only d3 right now so still have a bit to learn but it's how i currently feel and my enjoyment of the game has been diminishing the more i climb.
