I had initially turned it down to 3, actually. Now I need it at 7 or 8, and it feels mostly like the Destiny I remember. Running strikes and leading in kills despite having very little idea what our actual goal is since there are so many new ones.
It's the only FPS I've been so efficient in kills and that's always been part of the draw for me. Especially compared to how suck ass I am at anything besides support in Apex.
