I'd second the main issue being class design. I'm happy with the world, economy, friction etc. I was never going to be able to no-life or even consistently group so my expectations there were low. For me though a big draw to these games is having solid cohesive class identity and they absolutely nuked that like 2 months before EA release. Instead of fixing what they had they basically hit reset... Then half way through the reworks they seemingly realized it wasn't a great idea and some of the better reworks likes Ranger or SK (basically did nothing) are simply reflavoring the existing kit with minimal changes.
They need to go back and do it again for a bunch of classes and.... To be frank approach it differently. Combine that with stuff like poorly balanced/thought out mechanics (% weapon ratio on skills is, IMO, pants-on-head if you fully normalize and ignore delay), too much randomness of abilities (3 damage ability hits, etc), and it seems to me balancing TTK backwards. Make the combat feel -good- damage wise, abilities shit harder than autos etc, then balance TTK off that.
None of that was doomer criticism. All of it is completely fixable with some time now that they're getting firehose feedback from paying customers. Game is good, content is very good, classes aren't in a good place and they know it.
Releasing Trolls is the real EA launch anyway.
Edit: I also suspect just a numbers pass could make some classes feel a LOT better so it might not even be design in some cases
