Best not to rush them. As a general rule, it takes time to make comic pages. I've never made a comic before, but I know a lot of effort goes into them, including deciding the next step, deciding the page layout, and actually drawing it. ^^ While comic pages don't necessarily need effort in the artwork, just the story, this person evidently puts that effort into both of these aspects. To rush the artist would mean to ask them to decrease the quality of the artwork, and possibly the quality of the story itself. Not trying to be rude or start an internet war, but rushing an artist is a bad idea. I get you're eager. I am, too. Maybe a better way to word what you're saying is, "Very excited for the next page of WRD!" As an artist myself (albeit with few watchers and a lack of posts on this site), it would cause me anxiety. Not every artist is this way, but it generally doesn't get you what you want faster either way.
Tl;Dr - Don't rush artists to put out content. You won't get what you want in return. It's good to be eager, but make sure you're not rushing the artist.
