By "versatilily", I think the OP had more in mind than "the ability to cause damage in several different ways." 4E gives that, so clealy that can't be the complaint.???
My 3.5 evoker had tons of versatility. Energy Spheres had entirely different application from Wingbind, which had totally different applications from Firebrand, which had a completely different application from Moonbow. No one spell does it all....well, Wish maybe.
I think the point is that all 4E wizards are basically evokers now.
