Thats insane to me, I have yet to see one drop. I guess I'm just not at that point yet (28 at 440ish iirc, I'm at work). I thought that weapons were using affixes yesterday, but then I started looking up other masterwork items and legendaries and realized that the Marksman Rifle "Thunderbolt of Yvenia" is unique (and still a blast) but the LMG and AR masterwork variants that I picked up last night have been a let down. I hated the legendary marksman rifle that you got for just playing the game. Its damage was terrible in comparison to LMG's or AR's that were leagues under its level. However, the LMG and AR variants I picked up last night hit for around ~523. Where as the Yvenia Marksman rifle was hitting for 1558 and casting a thunderbolt at 1860 damage at what seemed to be every 3-4 shots. Far out-pacing its rival weapons. Much less any combo damage from the lightning strikes. Spider Thing in the stronghold just melts on normal with that weapon. Looking at the rest of the list though, everything else that suits my play style seems to revolve around setting up your group or relying on them too.
Content is questionable. Three strongholds isnt enough, and needs to be three-four times that. Content is there in other parts of the game, however its bland. Its the same handful of goals throughout the entire game. I recall a bunch of games having this same problem at launch, though. So yes, I'm right there with you on needing more strongholds, and more imaginative content quickly-soon. I personally like the Interceptor, but have a reluctant desire to try out the Storm. They should have used the different javelin's as a jumping point for more quests and content. I can think of a huge chunk of QoL improvements for the game, but my main desire is that they would just add events that are happening now, or able to be triggered to the map.
To me, they nailed the shit out of the whole flight and fight. Which has got my attention, but they've gotta give us something to do.
