The most basic wireframes will be just boxes everywhere and I label the boxes, say 'Pricing Plan Feature'.
Next iteration, would be wireframe still but all the copy need to be clear and thought out ie: the tag line would be 'Pricing Plan Feature' with a sentence below it like 'Our Plan fits any budget, from $5/month to $100/month' and be in that wireframe.
When people wireframe with lorem ipsum/line blocks, giving no indication of what would/is there, it can create assumptions and confusion - for your team mates/clients. If you say it's just for layout, then just use boxes with labels - anything else is just distraction.
When I get the copy after the wireframe, it can be frustation to get handed an essay and try to fit it in a space designed for a paragraph.
Always design around the content/copy, even at the wireframe stage. Knowing the exact (or close to it) copy/content the better - allowing you to gauge the layout and spacing more accurately.
