I know that, that's what I tried to say by the second part of my post. "Evocation at Thaumaturgy speed" however would still behave like evocation, at least in my opinion. Thaumaturgy is so much more than just slow evocations, so you would not have to think in evocations ways, that was pretty much all I wanted to point out.
Good point, I wasn't thinking about it that way.
