After the 4.14 path Lee Sin has been in my honest opinion fairly bad. Stacked up against other early agro junglers (Vi, J4, RekSai) he lacks utility, scaling, and base defensive stats. What he gets in return is a slightly stronger level 3 (barely). I think riot should look into some small buffs along the lines of Tempest/Cripple base damage or returning the attack speed slow.

I hope.
RogueWill1 votesJ4 is penalized by awful clearing times, Vi loses at lvl 2 and lvl 3 (lee sin is stronger) and rek'sai, well he is on the overpowered side of the balance (he is getting nerfed soon i think) . Lee sin isn't under powered on the slightly bit, however if you compare him with his previous patch it may seems like it since he was overpowered before.

RogueWill1 votesIf you consider power alone perhaps but lee sin has far more utility as a champ. J4 is more of a stiff champ, unless your opponents are over extended his ganks aren't as reliable (since your hard cc and gap closer is the same thing). Vi is more mobile and can hold her own but she falls down mid game and her sustain in the jungle isn't the best. Lee Sin kit works better for pressuring lanes and snowballing from there, his ganks are quite scary and if your lane partner supports you is a secure kill every time. New season however has diminished severely the ability to do this and hence you feel lee sin under powered. Grab a poche upgrade and make the enemy jungle miserable and you would see his 2 min windows is a really scary thing.
