I feel there are 2 types of PvP in this game..
1. DZ - You need a group to enjoy this. Else it will just be you getting mowed down for fun by other fully equipped 4 man rogue groups. Here the gear stats remain the same as what you have built it to be.
2. Last Stand/Skirmish - Here you need not be in a group. But your gear stats are normalized so that every one is on a level playing field. So you just need to have the right talents and attributes on your gear to be good.
I mostly play Last Stand/Skirmish, mainly because of not having any group to play with in the DZ. But I enjoy last stand a lot and it feels kind of satisfying to kill players ranked higher than mine when I benefit from the gear stats being normalized.
The only PvE I do these days are the legendary missions/incursions for the exotic caches, as they contain good amount of div tech. Also grinding resistance with players from Division discord, searching for the final piece of my Strikers gear.
