I like your guide and all, but in lane you should build to counter your opponent. So if it's kennen, you might want to buy a megatron cloak instead of frozen heart parts.
Because buying a negatron cloak or chainvest has no impact on the lane at all! You're completely right!
Souldevilj,
E - Q - W -> Harrasing on lane.
I usually use Q - W to harras, works pretty well.
Why not W - Q, because after Q you put silence to a person and it is more like bonus dmg.
As soon as you get R, go agressive.
E - Q - R - W + ignite = dead.
Build:
Doran's ring
Boots of speed + Mejai's Soulstealer
Catalyst The Protector
Blasting wand
Rabadons deathcap / Rod of ages.
All other items are up to the other team.
