I dunno, but in general I get my WF drops together way more faster than in ED. WAY more. Like in: WF might take days - ED takes MONTHS. Try playing with friends. It usually increases your drops in several ways.
Oh believe me, I know. Ever since I stopped playing due to finding out about the XP splitting in this game, I went and got into Warframe. I'm now MR25.
And I think I'd rather do my grinds to Duke/Rear Admiral in Elite all over from scratch rather than subject myself further to the massive amounts of RNG nonsense that exists in WF, even with 'radsharing' and other such things. DE are absolutely one of the worst sinners I've ever seen when it comes to over-use of RNG. Still second to Wargaming, but they're not far behind.

Testing gameplay (or workflow in my field) is intended to make sure the pieces fit together in a way that makes sense. It'll throw up some of the bugs, sure, but that's not it's primary purpose. Testing it early is difficult because you don't have all the pieces and often it's not until you have the jigsaw completed that you realize that the picture is ugly. At that point, the developer has two choices - either put some bandaids over the worst bits and release what you have, or throw the whole thing out and start again, knowing that you'll be months late on the project.
In an open-world game like ED there are so many different styles of play - even if they follow the same gameplay loop - that it's incredibly difficult to create something that works for everyone.
Still not a reason to at least make an effort. There's no harm that could be done by introducing dedicated & trusted players and community members to the design table.
I think it is very often the case, no matter what game you're talking about, that development teams do not have the same perspective as someone who lives and breathes the content they put out, and that without opening themselves up to that perspective, things that seem like glaring flaws and a clear trip down a rabbit hole will, to the development team, seem trivial or nonconsequential.
It doesn't need to be perfect, and sure it's difficult to create something that works for everyone - but that's precisely what makes it worth striving for.
