I'm facing this issue as well. Too many short, addictive videos being recommended instead of the ones included in the channels I subscribed to. I'm going to include yt in my subscriptions.
I'd kill for YouTube to start recommending short videos again. All I get recommended now are 20 minutes worth of content on something interesting stretched out to an hour long video. The recommendation algorithm seems to prioritize longer-form content, but the result has been creators being pushed to streeeeeetch and that usually means not editing down stuff that ought to be edited out.
In my case, the short videos I'm talking about are things like Dragon Ball Z scenes and GTA V screw arounds. Yt will now and then show me one of those on my page and, if I watch one, it starts to flood the page with similar content.
