You may think 4 is, but it's not. WOTC gets to review all works, meaning if they approve it, you're clear for publishing regardless of any change that occurs between their approval and printing. Seeing as WOTC approval would be the last step before you lay it out and send it to print, it's basically a non-issue. If they have changed it, they'll reject your publication. The chances of them changing it are pretty slim. There's no risk here.
