I personally also really like the game mechanics compared to D1. People are saying you feel underpowered in PVE and slower movement than destiny 1 which is true. But in my opinion its not a bad thing. We were way too overpowered in Destiny 1. There was not a single moment in the whole three years where I found a mission that wasn't challenging or that pushed me into a corner with a state of desperation, low on ammo, needing to think who is important to kill first and advance my position. You always just ran through everything, or to make it faster, pull that heavy and just blow everything up cause theres plenty everywhere. So I'm really looking forward to the story, campaign missions, strikes, and raid this time around. I think it'll be more challenging which is gonna be a great thing.
