User blog comment:ClariS/Why Xerath's Passive is Bad/@comment-69.141.8.150-20130318014932/@comment-4929329-20130320033135

Now you're saying that because people commonly build these items on Xerath, it is automatically a common Xerath build. Seems legit as well. "Proof" can be accomplished through thinking as well as pictures, you know... Mathematics does it all the time, and League is just a compilation of equations.

There's no kind way to say it, but... Xerath is the only tanky long range AoE nuker in the game... so he is quite special. Your association of builds between champions is as strong as saying "Renekton is melee and uses autoattacks to build up his secondary stat. Kassadin does the same thing, so he should build Black Cleaver as well." Trying to justify your response by saying that one uses AD and the other uses AP is silly because they're still significantly different champions, and Xerath is unique among his caste - there is no other champion in the game that has that kind of range with that kind of durability, period!
