league is an unbalanced game. 3v3's

How is the game balanced at all when there are champions like , and who kill the enemy jungler in like 3 to 4 seconds as soon as you see them? There's almost no time to react. You can try to escape, but they end up sticking to you, stealing your jg and killing allies in your lane. Even when I get a good team, there's always that one champion who literally does not fuking die like , , or . It's like fighting a 4v3. udyr, xin and yi sit in your bush waiting for you because they farm their jg so fast it's not even remotely balanced. even after a ghost poro in bush they disarm it and keep invading every 10 to 20 seconds. This is really getting old playing against a broken champion or being forced to play them and not play to have fun. This game has way too much try hard pressure and competition involved. Reminds me of season 3 and 4 when last whisper had more damage when rushed on pantheon and I could stomp enemies the same way i'm being raped now. It's a frustrating hell hole for many unlucky players who are perma stuck in low elo. I swear the only ones who can climb to high plat or diamond have some kind of god given talent with giant shoulders or are just lucky enough to be where their skill level brings them instead of getting trolled consistently. Maybe someone can shed some light on how to avoid getting asss raped by these hyper junglers and undying champions. Especially when they invade constantly. I can only ban one champion ffs.
