Not know how to farm and etc has nothing to do with team comp... This is extremely basic, Amumu, Malphite, Shen, Blitzcrank are nearly always banned from ranked.

This has no real information. Amumu is not even too mana dependant so any mid is good with him (if he's not banned by some miracle). Has nothing in initiation, CC, AoE damage, assassins, missing like half of the supports or more, which IS teamcomp. This is just blabber.

This is a good basic guide. I upvoted.

maybe it is basic to you, but i see many players (i only play ranked) and they don't know these kind of things and they don't farm etc. I hope i can tell some things to players who are not as well informed as you are :)

This is extreeeeeeeeemely basic. No up or down vote, somehow it's just not quite there to qualify as a 'good guide'.
