If we're looking at the design factor, Blizzard has been using centered text for the Dragonflight feature overviews. These overviews did not do any zone highlights (which were instead a part of the strange roundtable), but more of a general overview.
They
did use this bottom justified text for the Shadowlands feature overviews, which highlighted the zones/afterlives. That being said, it's interesting they chose to specify "Avaloren" over each individual zone, which I suppose makes sense with it being a brand new continent reveal, but it would imply that there are other key features they'd want to highlight.
