Let me put it this way:
It is much easier for a Wizard to prepare for a Warlock that he knows is a Warlock than for a Warlock to prepare for a Wizard that he knows is a Wizard (assuming they are opponents). The Globe of Invulnerability is pretty sweet at stopping the Warlock's powers. All the Warlock can do is run away, wait out the spell duration, and try again (and hope the Wizard doesn't have scrolls of this spell prepared, multiple memorizations, etc.)
