If you ever played as Rogue in WoW, you know that you can play Subtlety Rogue. Shaku's playstyle acts like one. He wants to sneak up for his prey and try to slay it in a single combo. They also have Finishing Moves to finish opponents or maybe also retreat. Shaku definitely has it all.

When you play him, he's like a little Illidan. Your goal is to smash buttons on your keyboard to successfully damage your foe. If you're lucky enough, you can just go ham. But then, you have Finnishing Moves that allow you to retreat if neccesary. Well, you will still usually use them to maximilize your damage output. Kidney Shot and Nightblade do that very well.

Playing as Shaku is not that easy. Whereas you have your ways to sneak up to your opponent, you will struggle against prepared enemies as they can shut down your chances to do your E+W+Q combo and, especially, your chances to activate your key to safety, which is any Finishing Move you've chosen. You might sometimes need to pretty much sacrifice your much higher damage output (Shadow Strike) for more safety once again (Smoke Bomb). But don't worry, if you've chosen a lvl 20 talent for Smoke Bomb, you can still deal decent damage to enemies.
