Someone Tell Me About Urgot

Evening everyone,
I have a rather narrow set of champions that I play on a regular basis, but I would like to think I understand the general mechanics or play style of just about all champions. Or at the very least, I know what's coming at me when I see them on the enemy team. Even Yorick, who is famous for being the least played champion out there, I feel like I understand rather well.
However, I don't think I have been in a game with an Urgot in maybe over a year. And if I was, I would have no idea what to expect. Obviously I could read on his website about his abilities, but really I'm more interested in hearing about the play-style of an Urgot main, what its like to play this champion, and why it is that so few people play this champion.
I'd love to hear from anyone with experience with the champ so please don't be afraid to reply if you only play him on occasion.
Thanks to all!

has higher ad than him)
Range is small
Semi-hybrid scaling that makes you have to buy a lot of ap if you want to make use of his shield
Very mana hungry
Immobile
Ult is only good when your team can kill an important enemy during the suppression (ie bad for most solo kill situations)
Very low damage at early levels (Has to get fed early)
Not good as a tank either because his protection/disruption skills are close to none
