I never did get into pvp in destiny, I was a lower level and I kept getting put up against people way above my level, felt like I was barely scratching them.
Did you ever consider gitting gud?
I did, played through the story mode and did strikes to level up to the max level, had a really fun time, but even then I still felt like there was something I was missing in terms of how the game worked.
In terms of FPS I like to try and experiment, figuring out how much lead you need to drop somebody in a game of halo, I'm the kind of person getting friends together to test stuff, shooting at angles to figure out how to properly lead, how to throw a grenade to better flip a warthog, or how to chuck a grenade high into the air for max distance. what it boils down to is "I wonder how I can stick my friend with this grenade when he's all the way up there and I'm all the way down here." *Looks over to a small pile of grenades*
