It draws too much attention to itself to be body text, yes. It requires the reader scan the letters more than recognizing the shapes of words and moving on. (Yes, this is why we miss misspellings and even missing words. It isn't my job as a reader to catch that. The author should have a spellcheck program and, if it's at all serious, a human proofreader.)
There's a reason there's a distinction between fonts for body text and title text: Body text is all pretty simple, uniform, and easy to just scan through. Title text is meant to be a logo in its own right, more difficult to read, and therefore take up more of your time. Comic Sans is, arguably, a reasonable title text font. It isn't for body text. It's meant to ape handwritten text in comic speech balloons, but if you look at actual good handwriting, it looks more like body text than title text.
