I've given my comments in previous postings, but I'll give it to you here too.
While I can understand that many will like this new system, there are some that don't like things that were removed.
Here are my bullets:
I don't like the removal of the old alert system.
I don't like how Cephalon Simaris Synthesis Targets no longer display the name of the designated target.
I don't like that I can't completely silence Nora - as when the you happen to complete one of the "challenges" as I don't even pay attention to what the target is.
I don't like that the extra little side quest for more Affinity like slide kills and etc. was removed and replaced with Nora's Nightwave.
I don't like the change where I have to switch out of the displaying of Nightwave so I can see Resource Drones display. If anything these should be reversed.
Personally, I would rather see Nightwave be more in line with the other "Alerts" on the Nav screen, where you have the option to do Nightwave along with Quests, Alerts, Invasions, etc..
Being more of a casual player, it took convincing from friends to get me to play this game, as when I checked it out it had way to much going on and no clear explanations of the many aspects of the game. Once my friends walked me through much of the gameplay I started to enjoy the game, as I wasn't being forced into things in order to advance.
This past year you have added a number of new things, which was overall good, but I haven't participated in much - like Orb Vallis - as I didn't really need to in order to continue playing the way I liked. Nightwave has changed things that totally affect my play time, so I am loosing interest.
Don't know if you can see how much I have invested, but ... my interest is waning.
