Junglers get too much gold and xp compared to the laners
I would often see junglers have as much or more cs than the laners. They would also be higher level. I feel like a jungler is kind of a second support and laners are the people who want to farm, get xp, and gold.
I suggest change the spawn timers of jungle from whatever time is now to about 1 min. And then nerf how much xp and gold the jungle monster give and this way heavy farms can still go a heavy farm route and junglers who gank wont be at a disadvantage.
Also, I thought I might add that junglers who start red and take the golems have a huge advantage compared to junglers who need blue buff because they get level 3 much faster than the blue buff junglers. I think that golems need nerfs or gromp needs a buff. But if you buff gromp, junglers will have more power so krugs will probably need a nerf.
