The story of Destiny is matched, IMO, only by the gameplay and controls. In that regard Bungie had it nailed from Day 1. No shooter before or, frankly, after, has ever felt so tight, so dead on perfect to me. And now we have a story that matches. Lore deep enough for individuals like Byf to make hundreds of hours going over. True character progress where we see humanity in the alien races around.
For all it is a guns and space magic game, Destiny is a fantastic science fantasy voyage that just keeps getting better with every update.
As far as gameplay goes, with my new job, my shitty hours, and taking a ton of classes, I have not had much in the way of time to play. I do need to get some work on on this season. I only barely got the title for last. Life is really interfering with my game time.
That said, arc has always been my favorite element for titans. I've been an arc main from D1. Arc 3.0, like the other enhanced classes, is excellent. I love the versatility we have and while I do miss the invincibility I had with pre nerf Lorelei and Solar, I think when I have the time to really do some build crafting Arc is going to be just as tanky, but perhaps with a bit more punch.
I love the movement, the speed. I enjoy being the fastest thing on the field, even without maxed mobility.
I'm not big on the armor this season, but the pirate activities are quite fun. Way more than grinding through a thousand containments on Leviathan.
