You need to explain why you take defensive runes instead of mana and MP5 in utility. I also find that morello's is not as effective as other items, the only reason you say you take it is for CDR. It IS nice to have some CDR, but you do not need to spam abilities to get voidlings out.

Your guide is a good start, but need work. It is a bit hard to read with no mobafire coding. It also lacks some basic explanation of abilities or strategy. Expand on what you have.
