Urgot is squishy if you can catch him unawares...
I had a recent game against an Urgot...
He played solobot versus me (Cho'Gath) and a noob Miss Fortune...
Obviously I am playing on a far lower level than any of you, so it isn't as applicable or impressive, but he was solo laning nicely, killing our Miss Fortune and getting fed and stuff.
It took 3v1 to root him out, and he nearly killed me when he swapped me towards his tower...
Ugh, good thing Cho'Gath functions well under pressure...
Also, I've found that grabbing an Urgot with multiple Ruptures early-game can cause an early kill, because he depends on his abilities to survive, and hitting him with things while he's in the air is very painful for him.
If I got close to Urgot, (which was harder than I thought while he dodged my Ruptures) I could Feast on him for a kill, as Feast took away over half of his health.
I imagine that the Urgot I was playing against was a noob, as everyone's a noob down here at the level 10 range, but I noticed several things about Urgot that are important. (at least to me... I dunno about anyone else)
1. he is a great harasser, dealing tons of damage from afar.
2. if anyone stuns him or gets close to him, he has a hard time escaping without teammate intervention.
3. Kassadin beats him in DPS, though it all depends on who is faster at clicking on stuff... (surprise teleport, null sphere, force pulse, nether blade, deathfire grasp, death.) Urgot dies rather consistently to Kassadin's nuke-yness, but Kassadin has a little trouble if Urgot is near other teammates.
4. Cho'Gath is a fun counter if they aren't paying attention to Ruptures...
5. Again, it seems that Urgot is a seriously good team player, and he NEEDS teammates to stay alive and deal out his "tons of damage."
6. Shaco and Urgot make a great team... (Shaco makes JiBs in a bush, Urgot swaps places and the JiBs kill the player) and apparently (according to a friend, a meh 1200 ELO jungle Shaco player) this is the only situation in which Shaco should (could) be laning...
And again, my brain has vomited out some more useless points onto a page.
Forgive my intrusion...
