Urgot's itemization is horrendously limited
to the point where his only real AD item that can be called core is
and he is effectively disbarred from any other juggernaut items. Can't buy Sterak's, or Titanic, and Triforce is obviously out of the question because of how his kit works. Attack speed items are not good because he actually loses DPS by buying them if he ever uses W.
is situationally strong but not worth purchasing every game, same for
. His rune options are pretty mediocre between Aftershock, Comet, and Spellbook, but that's a different problem.
If Urgot wants to itemize more offensively than Cleaver-fulltank, then he has to dip into other classes' items, a problem that existed for fighters a long time ago and was the reason we got items like Sterak's in the first place. Namely assassin items, Ghostblade and Duskblade (there's actually a Korean Urgot buying both of these and doing really well in high elo)
I'd like to be able to build my juggernaut like he's a juggernaut, though, and not an assassin. thx
comes immediately to mind; he would have pretty insane area damage with it. Sterak's on Urgot would also be incredibly good on him, since he has a total AD ratio on quite literally everything. Plus, things like conqueror and grasp would be really hard to deal with when fighting him (if you're purely melee; he outranges you while maintaining conqueror through his W, or he would constantly be getting full grasp procs on you while you can't retaliate without going in on him.)
...
and its upgrades would interact with his W might have had something to do with it.
windwall and
Ult.
run down over
due the true damage while before it always used to be a skilled match not sudden death from pop true damage.
and
or 
does NOT use Conqueror, Why? Because it sucks and its not viable with its current numbers
