That's from Dragon Mag, right?
If so: Please keep in mind that's not "core", and not accepted by many DMs. Me, for instance.
It's legal enough for the RPGA.
But regardless, the point still stands that doubling up on the same defense in your at-wills is weak.

Good holy lord, Thunderwave and Ray of Frost are not the same freaking power. You have two freaking at wills and if you choose both of these, both being the heaviest control and lowest damage/range you will be hitting fortitude and only fortitude.
Which is why I suggest you don't. Because that's setting yourself up to be gimped in the very brute fights you mentioned. You can -choose- not to be gimped for those fights, and prepared for a more all-rouned offensive. Or, you can -choose- to be gimped for those fights, forgetting that barring the spending of an action point, you can only use one at-will a round anyways. So there's no point c-c-c-comboing them up, and instead looking for combos with your heavier hitting powers, so your action points are used for the most awesome.
I'd suggest Scorching Burst and Ray of Frost, or Thunderwave and Scorching Burst, or Thunderwave and Magic Missle, or Thunderwave and Cloud of Daggers. I would NOT suggest Ray of Frost and Thunderwave because of the defense gimpery that'll hurt you in the long term. If you're human, then you can go Tunderwave, Ray of Frost, and third power of your choice, and that's all kosher. But if you're not, you're not so hard up for control that you -need- both Thunderwave AND Ray of Frost. Pick one, or the other.
A decent build you can do from the start is a Human Wizard, go
Str 10, Con 14, Dex 10, Int 18, Wis 15, Cha 10
Staff of Defense
Feats: Action Surge; Improved Initiative
At Wills: Thunderwave, Cloud of Daggers, Ray of Frost
Encounter: Icy Terrain
Daily: Flaming Sphere, Sleep
A Staff of Winter will go a long way to keeping you safe. Automatically immobing enemies around you once per day without an attack roll is a decent thing to have. Later, a Thunderwave Staff is a great combo with Thunderwave (who knew?) and can turn it, once per day, into a damage powerhouse. Once you get to the vaulted 30th level, your wisdom will be at a respectable 23, 25 if you go Demigod, which will mean that Daily Thunderwave Staff hit will make that Thunderwave a 8d6 blast that knocks them prone.
