Well, it's terrible overall.
I started a new char with a friend at steam release and we're doing quests. 15 hours in we found out we can play the legacy campaigns through some random NPC.
I told him the whole time I don't understand whats going on, since the last time I played the tower was destroyed or something (played beta and some hours on bnet). We did the introduction quests and now are trapped with only fetch quests (kill 100 of that, kill 200 with this, bla). Story until now basically non existent. Meh.
And then all of these other shortcomings on top. You have to claim your archievements/triumphs to show up. No way to see what strike you already did then having your mate checking the triumphs while you stay in the map overview. The map (Destinations) still feels like a straight D1 port. No zoom, no infos, no nothing. Snapping back to the center if your mouse leaves the border. Like yeah, this is a bad console port, we get it... but why so terri-bad? Then there are a shitload of icons on the destination map beside the planets and no tooltip or anything. I don't understand what they are trying to tell me.
Same with the quest log. No explanations at all. Tracking doesn't do shit. ...
I remember back then with D1 you had to read the web to understand the lore at all, but now you need a wiki to get the basics figured out? Meh. Gunplay is fun, no doubt, but the other 80% of the game are not.
And why are there so many MTX when you have to buy the current expansions for more then 50€?
Why kill 80% of the content by boosting and leaving you with some dull hours of fetch-quests until the point where you need to buy the expansions? Eh.
