User blog comment:Mineko Charat Lucky/Stop Telling Me What to Build, Thanks/@comment-4434378-20131015182203

Because so often people just build things that are quite obvious noob traps. Or that just don't make any sense at all. Spectral Wraith on Rammus for instance, is pretty awful; the only case where it really shines is if you hit numerous targets with your ultimate, otherwise you are hampering yourself by not having the Tenacity of Ancient Golem (especially for a champ that needs tenacity as badly as Rammus). And if threat is what you are after, then Sunfire cape is going to add more than the 40 AP on wraith.

I've seen Blade of the Ruined King graves, I've seen Mercury treads Sona and I can't even remember the last time I saw a Teemo who built something that made sense.

Its difficult to explain to people why certain items are just not worth it, especially in the context of a stressful match.
