Wizard OP / no counter play

Ever since Legacy, Wizards have been one shot comboing… Why design a class dependent on one shot combos?

In addition, there’s zero counter play to a Wizard as a Priest. Scepter is unable to target the blue recall orb, so you’re forced to eat a one shot combo. And Staff projectile speed is so slow they can get the teleport off in time to one shot combo.

Is this really intended and balanced in the devs’ eyes?
