Playing one of those strats will improve your Micro a great deal.
The next important part is "Play agressive!"
Quote: "Play aggressively; avoid static defenses. [NeoBlade: 1-2 Cannons is ok, if you have to defend Drop-Play, DTs and so on]"
When you play aggressive your Multitasking will improve and you will be able to scout the front more often.
