You can almost never afford to use your W in trades as a lane Sion, especially not if you're expecting a long laning phase until you back. While the damage is solid at most stages of the game and it blocks damage, it can generally not do both in the early/early-midgame ever since they nerfed the rank 1 shield. It's typically used to help push up or deal more damage to/zone your enemy laner when you can spare the mana.

In actual fighting with other champions in lane, you only tend to use it either when you've got a break in the action that you expect to be long enough for you to be able to actually blow the shield, or to mitigate damage when you're in danger.

As long as you avoid using your W too much, you should be able to last pretty long in lane, especially if you started flask.
