Hear me out on this one. Before H&H, entering the Swamps was difficult, but with some preparations it could go relatively well. Maybe you found a draugr village and got some entrails? That let you make some sausages right off the bat with materials you got in the meadows/black forest. If not, you fought Draugr right away at the boundary of the swamp, so same outcome.
Before H&H, experienced players knew to spend time in their first swamp forays to find the ever elusive turnip plant, then usually go home and farm them like crazy to have a good amount of turnip stew. You could eat sausages while looking, making survivability do-able.
Now, turnips are required BEFORE you can make sausages. You need them to upgrade your cauldron. You still need them to make Turnip stew. You also need them for Black Soup. In fact, basically the only swamp tier food that doesn't require Turnips in some way is a Muckshake; a low health medium stamina food. So apparently, Turnips are way more important than they were before (and they were already pretty significant before).
All this being said, turnip spawns seem as low as ever. I've just checked out 4 different sizable swamps in my seed, and only the 4th one had any turnips in it (it had 3! but they were all in one spot in a relatively large swamp… think 15 or so crypts). So I checked (using cheats) some other seeds randomly created. Of the 5 I checked, 4 of them had a similar problem, in the 5th turnips were found in the 2nd swamp nearest the spawn. More than that, the art rendering of turnip plants doesn't particularly stand out, meaning a player might not even see it when it's there. Contrast this with, say, carrots in the Black forest.
So my question here is obviously relatively simple: if turnips are now so important, why the devil do they still seem to spawn so rarely? Fortunately, I can think of two simple fixes. 1. Stop all the damn turnip gating OR 2. Let turnips grow a lot more so they are as commonly found (or nearly) as carrots.
