as people below me have said, AP mages are kind of out of vouge right now, so anti-mages (Galio, Veigar... but mysteriously not Kassadin) are also out, since they're not as good when the other team is AD Bruiser Top, AD Assassin Mid, AD Jungler, ADC, and AP Support (who doesn't do enough damage to bother countering).

basically he's good but not in the meta... but just wait for someone in the LCS to use him, and he'll be popular again, probably
