good list or nah?

Granted I'm a Sej main but if you can survive the early, she's a good champ mid and a monster late game. Just had a game where all but one lane was feeding. I got to late game and had tag team with a Leona. She would set the engagment and I would hang back a moment to catch those who tried to dive the adc. She's absolutely monsterous.
Is this current or opinion?
Because
exist.
Also no list is complete without the queen. 
Since, Rammus and WW are on there I'd assume this is a list of champions you play?
You might want a scaling jungler then if you want to make these your go to champs. Most of those except Rammus hit a cliff after 25 min if they are not fed. J4 will always be useful with that ult as a tank.
It's a decent list if you like playing around early/midgame. If they are ranked in that order elise is much higher probably #4.
I think that Kayn is the best jungler. a)his ganks and flanks are awesome b) he has 2 forms and each is highly useful c) he is very fun to play
Are all considered top junglers last I checked but I've been in the field for a month so I might be a little behind the times but I wouldn't say the list is bad as I play most of the champions you mentioned myself regularly I would definitely put my girl
higher on the list but that may be biased.
yo
is the best his ganks are great because of his q and can exicute with his w
