Yeah, it is. They’ve been on a skeleton crew since the BfA alpha. All those layoffs hit hard when the best employees left to avoid the next round. It’s the top producers who have gone. Given Blizzard’s reputation as being glacially slow to respond to the need for change, they’re probably unable to produce any real content at this point.
After they hire all those replacements they’re advertising for, it’s going to months before they get trained and up to speed. So nobody should expect the next patch to come out any sooner or have more content than this one.
