Why it think shyvana can't be strong unless renekton level constant buffs

I was a shyvana main. I still play her in ranked for fun since I enjoy her but she isn't optimal. She is one of the successful degenerate champions. That doesn't mean they are good or bad. It means it limits what they can do with new champions and items since they have to account for them. Take sorraka for example. She is one of the worst offenders of a degenerate champion since she renders tradding pointless and is frustrating to play against. Riot has come out and said she's impossible to balance just like rengar. The reason shyvana is a degenerate champion when riot wants farm jg's to be good, this also includes shyvana. They have to make sure it's not going to cause udyr, shyvana, or yi to break the game. Shyvana has a highly balanced kit. She will stay at a 50% until divers get reworked. Nocturne suffers from the same thing. Successful degenerate champion with a super balanced kit. When he's strong, he terrorises carries. Also sitting at a 50%. Udyr and yi are still annoying in low elo. Shyvana can do the same shit as udyr but doesn't have as bad of a name since there are so many trick2g fanboys and she has no cc. She's basically diver udyr. Her clears are just as fast and can splitpush really good. Remember what happened when sated devour came out??? Everyone flipped a shit about shyvana and yi. Shyvana was being banned. I heard people saying she's a nasty jg. Tried her for my self as a shyvana main and I thought to myself fair and balanced after snowballing extremely hard just by constantly diving. Same thing happened with yi but he was already a common ban before that. Basically if they have a balanced kit, they release somthing that highly favors it, it shoots up in power. They buff the wrong stuff on shyvana. Riot seems to want her to be good but not broken. Now let's disscuss her play style. Shyvana is the textbook definition of a power farm jg. She can't gank until 6 without exhaust or blue smite. Even then she has shit ganks pre6. That's how all divers are like nocturne, ww, and yi. She is also a bruiser. The thing about shyvana that is detrimental to this kind of play style is she's feast or famine. The problem with that is she has a hard time with early kills so she needs to afk farm and beat the other jg. If it's someone who can deny alot of farm, shyvana can't do shit. If yi can keep up, he just stomps and she is pretty much the only one who can duel him to death since shyvana is an amazing duelist. Top doesn't work any better. It's worse. She shoves with w. Her e does crap damage. That's half her kit gone still the same diver bruiser. She's just in a weird spot where if she doesn't get touched up every few patches, she will become underpowered. It's at the point where she came revive major buffs unless riot wants a combine harvester with rocket boosters and lasers powered by a bazillion script kiddies taking Evey camp before her side can respawn 1 camp and set the jg on fire because smokey the bear. They also don't want another udyr. I'm surprised trick hasn't really played shyvana on a stream as a way to do somthing different since she is similar to udyr but no cc. Udyr takes towers so quickly and so does shyvana. She has never been popular. I haven't even seen her alot last time she was getting bans. Saw like 1 or 2 shyvana bans and 1 or 2 shyvana picks. In conclusion, shyvana is too balanced to be strong. They fiddle around with her but none of the changes fix anything. Someday she will have her days in the spotlight but now is not the time. I still can make her work though.
