Lol. no.
it is not an opinion, it is her legit gameplay style. you just look at a winrate and see "oh, is easy, braindead". take a good look at some high elo recorded games of shyvana. one single counterjungle invade is enough to fuck her up for at least 4 minutes into it, which for a jungler means the entire world.
if she gets behind and still tries to hard engage she will just end up feeding the adc.
You should at least know on what the stats rely with, not just read them and assume they mean something. Shyvana isn't as difficult as a champion, but if you have no gameknowledge and suck at map control you are bound to lose on her. and lose you will HARD.
I know her stats very well, i revisit champion.gg every patch and analyze any champion that has an above 49% winrate. you don't tell me i speak of opinion only when all you do is tell some stuff you think seems the most appealing. the Thing you did? THAT'S an opinion.
"Oh she has a high winrate, she must be braindead easy" is a very flawed sense of logic i highly disadvice to spread.
