So, any suggestion on how to "Improve" the Wizard's at-wills?When comparing at-wills for controllers, the wizard has some issues. His at-wills focus more on damage than control. The consensus is that controllers need a little more, well, control in their at-wills than we've handed out so far.
Vanguard's lightning is what I'd see as a baseline controller at-will, with scorching burst slightly *below* baseline. That little extra bit on vanguard's lightning is precisely the kind of thing that makes controllers go - they limit/mess up the enemy's plans.
Now, this may seem pretty annoying - WotC released stuff that was too weak! However, I think it's actually a strength of the meta systems of 4e. We've never before had the ability to so clearly compare classes/roles and, when necessary, make adjustments. It's a lot easier to listen to feedback, gather hard data, and make comparisons between powers when we have a unified power scale.
Can we expect to see this "fixed" with Arcane Power, introducing new Wizard At-Wills?
