I’m using Acrobat DC but I came from Acrobat Pro 6/7. Editing text in PDF on Acrobat 6/7 was almost perfect. On Acrobat DC working on same PDF files, is unworthy of a commercial product. Even editing a single character broke layout completely on DC. Same file on Acrobat 6/7 I could replace entire paragraphs without an issue. Even free apps perform better than DC on my files.

Btw, Word exporting is almost perfect and I can edit files as I want. But you should improve features, not destroy them.
