Okay, so this is the Build I'm usually using, more or less. I say usually, becauses it is very efficient against both tanks, dps and mages, but lacks in strength when I face foes such as Blitzcrank or Tristana, who can both close in to you very fast (or bring you to them, in Blitzcrank's case) and deal heavy damage when casting their spells. So it either works perfectly well, or sink you down, depending on which foes you face.

I'm actually working on the guide, so don't judge it just yet.
