I think plants CAN work but it needs these changes

• In general: Increase the hit boxes, increase warning times. Also, maybe this: you can only use it 15-30 seconds after it has entered your vision

The warning should be increased so that even if a plant is already in place there's a warning for where the next spawns.

The plants are also a pain to hit, I usually spend 14 seconds trying to aim the plant. Maybe change the UI and make it easier to auto?

Maybe to decrease the amount of 'rng saved me' moments, you have to constantly scout the plants to use them? Sure, it'll still save dumb people if they're paired with smart junglers and supports who constantly scout the plants, but in terms of how much skill they put in, it's the same as attacking gromp then flashing over a wall to finish off a low health person chasing, and it's also as much skill as having that smart jungler/support peel for them (and they don't notice, they're too focused on clicking with their screen locked) while they furiously right click to base.

• Blast cone: Can't use in combat, can only push allies, you must be in range to attack the plant.

This plant gives people the most problems, but it makes jungling as an immobile champion so much better, so remove its ability to be used in combat and make it a plant for easier jungle paths and stealing objectives with smite.

• Healing fruit: I don't know about what this one needs

It can heal laners if they need the sustain, which might come up as a problem, but it's also good for jungle sustain on some weaker or more mana reliant junglers. It also works as a slow so it's risky. I think this one's good because it encourages warding the river more often when everyone just wards lane bushes or risks deep warding until they expect baron/dragon.

• Vision: just nerf it

Good idea to have spots where warding is risky, (places where you use the plant and can quickly walk to the ward without fear of being attacked), but it also gives so much vision for the amount it denies. Make us pick one, nerf it, change it, just do something
