Managed to get the exotic Hunter helm finally. Now I look like Sam Fisher! :D Forever bad luck with Legendary engrams. The one Legendary I managed to get were Warlock boots...
Reviewers aren't looking far enough into the future of the game. It's like looking at the blueprint of the first motor vehicle and saying that it'll never replace a horse.
So long as they plan to implement expansions, which you could actually purchase the first two when you bought the game, and the season pass actually makes it a little cheaper, I don't see this game going away for a while.
What you will see is a slight decline before the expansions due to people speeding through content, decking out their character, and then chilling until next phase. Those that are on during the lull will be people who are taking it slow, or who enjoy PvP.
I was goofing around on the free roam earth section and ended up going from 17.5-18 in about 30 minutes. I was farming items for coin. I also ended up with a lvl17 rare pistol that rocks.
It's nice to go back to easy mode areas, still get the same xp/kill and have level relevant items drop.
There shouldn't be a decline. The PvP is still super fun except for all the assault rifle/shotgun combo scrubs and they're doing updates every month.
On the 16th there is going to be the first 6 man raid which will be super difficult. We will get an objective to do, but we will not be told how to complete it. We'll have to figure it out for ourselves.
There will also be an event this month called the Queen's Wrath. Don't know much about that one. I think capture the flag is coming to PvP as well next month. That's all I know so far, but it seems like quite a bit.
