Full Blender support for UE4 in 2019?

Out of fairness there are other issues to consider no matter how amazing blender is in totality
Unity blender support isn’t perfect as dragging in blend file doesn’t always work as I was hit with that recently, trying to bring in a basic stick character with rig but a fbx worked, shrug.
Another thing for which blender dev’s havent had time(?) to fix is the slow viewport, whereas 3ds max2020 is literaly KING there,I know from experience recently.

That isn’t to say I dont use blender, as I do have projets that work well, but my 2.5 mil tri mesh takes forever to go INTO edit mode, and when there forget doing any edits. It’s a known issue,thats been there for ages ,tho my understanding is they are working on it. No idea wha eta is supposedly nor IF this specific issue that affect many is going to be fixed.

Point: the blender use isn’t as simple as it seems. It may never affect those whose projects are <= 150 or so, but as the complexity increase so do the problems.
