That wouldn't surprise me. Wayne's been doing the covers for, what, 12 years now? It must get a bit old after a while.
I'd say the same here!!
Also probably unpopular onion: the color on Ravenpaw's Farewell isn't really a good one. I kinda wish there was something else decorating the covers, too – they seem a bit bare with just the text and the headshots. (I do like how the headshots look, though. I wonder if they'll use the new map art in these?)
It looks like the same colors as Tigerclaw's Fury, actually. I mean, given that these are novellas, and released only digitally, I wouldn't be surprised if we didn't get fancy covers.
