Urgot: 0.6% pick rate, 45.6% win rate.
I used to play Urgot from time to time, but the 5.22 patch left him with no mana sustain. Hes an AD castor, and blows through his mana about as fast as Syndra dose.
Hes got an a very old kit, but he gets the occasional update/change to keep him alive. Most recent the removal of armor and mr from his ult to straight damage resist...
I never played him in bottom lane as a marksman more than a few times (hes a bit weak there), I took him top and built a mix of damage and defense. I found he did much better there than in bot-lane. Even I have given up on him there now, the loss of early game mana sustain just makes him an immobile mana hungry champ laning against either sustain or burst damage champs.
Lee Sin is down sub 48% win rate with his 33% pick rate, so he will see buffs probably before Urgot. After all Lee has 6 skins to sell, and Urgot only has 2.
