Here is my level 87 (for now) wizard:

It's not pretty except when all the cooldowns are up and nothing can fly. I'm three martinis in and still have about 4 more to go, but I'll try to give wizard feedback in this post as well.
As a side note: My level 19 shaman has ice spells that do not so dissimilar damage to my icebolt. Seriously, my shaman is critting for 600 with his free ice spell, mine is critting for less than 1000 on my 87 decked out wizard that has all the caster gear a level 99 ranger and a level 98 monk can muster.
My biggest complaints are itemization. I can max haste in basically three slots, finding lots and lots of crit damage and crit % items in cloth with evocation is really hard and maybe not possible at this point in beta. If I could max haste past 100% and time travel back and cast before I press a button, then that would make the itemization great too, but right now I'm having trouble filling slots with useful items.
