FWIW, I know a few people who really do miss the dog-men kobolds. Mostly some real grogs, the sentiment is out there. And I would not be half-shocked to see them making an appearance in 5e.
And fat halflings have been missed since 3e.
4e made a lot more changes (the drider one specifically is not one of the more major ones, but it's one that got anchored in 4e), of course.
And it's not edition warring to hate on a given change that 4e wrought. Far from it, in fact -- edition warring is tribalistic sniping about how some edition sucks or is above criticism. Just saying that you don't like Change X is specific, narrow, and about the change, not about the edition.
Veterans of the Edition Wars sometimes have PTSD and jump at shadows.
Thank you so much for saying this!
