Honestly, with the majority of games being PVE, no wonder the game has been pretty mixed in reception. They've really pandered to their competitive audience which is fairly small, but vocal.
This is incorrect--campaign players are a major priority for us, but that content is not as "far along" or polished as other parts of the game because those have been in development longer and more thoroughly tested by players. Campaign is very fresh content--it was never part of our beta testing process, so this is the first time players outside of the studio have gotten their hands on it. The feedback we're getting now will help us make it better--that's one of the biggest benefits of Early Access.
Why didn't we focus on campaign first? Well, the team needed to build 1v1 first as it's foundational work; they then used those tools to build 3P co-op... which was then used to start building the campaign fairly recently. We still have the upcoming 3v3 mode and our editor coming as well. Back to PvE, I'd say that Campaign-focused players who want a more polished experience should check back with the game for 1.0 while we continue to expand and improve it.
