Took a bit of time to try out 2.0 and it was kinda fun, though I'm not sure all that much has really changed.
They say they've speeded up the gameplay a bit but it felt the same to me (though it's been a while since I last played).
I did like the changes to Tarot where you don't need to spend fate to do special Tarot missions, you just get to apply 1-3 Tarot cards to the regular random missions instead.
Crafting/gear has some new stuff to modify your items with, but it seems slow & expensive to accumulate compared to how quickly my gear becomes obsolete so I've not made use of it yet. I did get a blueprint for making Relic eye implants though, so end-game crafting may at least be worthwhile (for the most part that might be the only time it's worthwhile, from what I can tell).
Level cap has been raised to 100, but the vast majority of it is dead levels where you're just getting another skill point for those passive 1.5% bonuses.
Void Campaign is another option for a set of random missions, but this time with ramping difficulty and a limited number of losses - further through you get the more keys you get to open the loot chests at the very end.
Psyker still seems to be far more powerful than the rest.
I gather they adjusted the Warzone thing, but I haven't tried it yet.
And they're still as bad as ever about dealing with bugs - I had two missions I was unable to complete because of bugs, one where the npcs I was to rescue didn't register that they'd been registered and refused to follow me to the exit, and one because a bit of scenery was just slightly in the way preventing me from interacting with the objective. Both of which were bugs a year or more ago.
No idea if multiplayer is any better than it was - it was telling me it was unavailable when I tried queuing for coop with randoms, and I saw on the forums people complaining that a bug is eating their loot in coop, so yeah...
All in all about what I expected. It was fun to run through and smite some heretics again and I'll probably spend a bit more time in it here and there, but outside of the 40k feel there's several better ARPGs to be playing.
