Now let's look at why Xin is NOT strong.
 * Since his kit is mainly burst, he can do 1 combo and then has to wait.
 * He is a Melee character, highly susceptible to knock backs and CC.
 * His ult can be a team fight nightmare in the wrong hands.
 * He has no natural defenses to speak off, without using his ult.

Sure he's a great dueler assassin with good strength, but he does require skill to play. And in an experienced player's hand, not that hard to counter.
