I strongly recommend against playing
. Aside from his global teleportation ult, he's a MUCH LESS reliable and effective version of
.
does every thing he does in a team fight (protect carries, lock down carries) except better since his lock down abilities are point and click (while Shen has a dash you can easily miss). Also, Mao has better lane match-ups, more survivability in laning (wave clear and free sustain) and has a game-changing Ultimate.
The Shen Ultimate? You'll get to use it maybe ONCE before laning phase ends in the chaos of Solo Q. And your team must know how to play around the Shen Ult, which they won't in low elo. So you'll have times where you Ult in only to have your team walk the wrong way. Then you return to your tower a few EXP behind the ennemy laner. Also, it SUCKS to lane as Shen with only 3 combat abilities while the other laner has 4. He has a non-combat Ultimate.
The pro strat of splitting late game with Shen and then Ulting to your team is not going to fly in Solo Q most of the time either (people simply can't adapt to this style). But if you group up... you're basically a less reliable version of other tanks like
and
.
