The lategame problems: He's not as inherently tanky as other people, and his bases aren't as great. While a fling and a good single target nuke are nice, he's not bringing the kind of AoE damage that Skarner or Shyv or Maokai will, or the AoE CC and single target deeps that Lee Sin will. The fact that his ult is a good on hit for magic damage but, being magic damage, scales terribly as people tank up is also problematic.
In general, I see him considered as OK; not good enough to justify nerfs and not bad enough to justify buffs. He basically brings decent, but not amazing strength everywhere.
