I've seen "no new class/race" mentioned often as one of the reasons many players, hardcore and casual alike, think that Shadowlands is "filler".
Plenty of threads about the class, but do you think that they should add playable races sometime during the expansion to counteract this look? Keep in mind that Blizzard will add and/or change any lore that keeps Shadowlands races from walking with mortals, though that is a point of contention for many.
