Biggest class impact from Velious

[nuuki]

There are several threads from years ago that mention some changes that Velious brings to the class dynamic, but am curious what you guys believe the most impacted classes are from both a positive and negative angles?

Wizard - from bottom 3 to top 3? Is this true?
Ranger - from last to pretty useful in raids?

Are there any other major transformations caused by the Velious release? If so, what caused them?
