They aren't so small that they can't devote time to fixing issues. The problem is not with their size or their ability. It's with their priorities. If they would spend more time on existing features before moving on to new features, then they could fix issues with those features so that they aren't broken when they move on to new features. It would also help if DE's devs (as in, the actual devs, not the community team) played their own game, so that they were aware of these issues (and no, it's not enough for players to point out issues because they clearly overlook or ignore a lot of the feedback players give, otherwise many years-old issues would be fixed).
