The jungle meta is the WORST meta in all of league
At least when any other role is strong (Top, Mid, ADC, or hypothetically support) there's counterplay around it. Your team can give up areas on the rest of the map to shut down that lane because they're always in a predictable spot.
When junglers are OP though? And I mean all of them (there's a reason smite is getting nerfed) there's nothing you can do. Yellow trinket has a cooldown of 3x it's uptime at level 1. That means 2/3 of the time in early laning phase you won't have vision unless you can keep a control ward active. Then add in that any jungler can gank full health at level 3, and can just go for kills non-stop. It's quite ridiculous really. Now you suddenly have a fed jungler who you can't find and just hard carries the match.
3 winning lanes = a lost game. Because your jungler can't gank for a winning lane (can't tower dive at levels 1-3) and only has a 1/3 chance of correctly guessing the countergank.
I feel like some stuff like this smite nerf should have been hotfixed. It's pretty clear that junglers are just out of their minds right now - a jungler should not be outleveling solo lanes when they have safe and reliable xp as opposed to interactive play against an opponent and the fear of a 2v1 emerging at any point. Carrying from a lane is already inherently much harder due to the need to respect the jungler and taking a risk whenever you go for a solo kill - giving junglers the ability to have a level advantage on top of that is absurd...
