I like the build, but don't have WF. So I whipped this up quick as a Drow alternative and I was wondering what you guys thought. It's more or less a carbon copy of the one listed above, just smarter and much better looking.

I haven't played an arcane caster long enough to get past the harbor quests (because I've sucked at making them) and would like some feedback from someone who has before I waste more time on a crappy build.
[snip]
This build improves on the WF design in a few areas (saves you a feat on reflex saves, allows you to use OL instead of using SP for Knock) while taking some hits in other areas (less HP, can't heal/repair itself, generally poorer at soloing). While it would be fun to be a soloing wizard, I think in the end the costs and benefits of the switch to Drow balance out.
In combat this build would be played as support, focusing on controlling the field with spells like Web, Sleet Storm, WOF, etc. Instead of trying to rack up kills, the goal is to take pressure off of the tanks by immobilizing, controlling, or weakening mobs. Of course, my metamagics are probably wrong for that purpose so some help with those would be appreciated. Then if sp runs, I can switch to a shortbow or crossbow and still feel like I'm contributing something.
Thoughts?
