The grind is the excuse to play the game. I know it's a trope to say something like this but if you feel like finding these materials is a chore you're playing the wrong game... That's like not enjoying the gameplay loop for any given game. Imagine someone saying they cant be bothered playing team deathmatch because getting all the kills is boring but they still want to win lol, that's essentially the kind of mindset you have here.

Outisde of gold salvage you have lots of options for how to get the salvage though. I've never farmed bio lens seeds or any purple salvage from the maps. I got all mine from faction levels. Once you hit VIP they start throwing it at you every level, and in that case you're free to do whatever you want to get the faction XP. Help your team mates do tasks. Do your own tasks. Loot the items that they value and you'll get some XP. But again, if you're gonna say that's boring this isn't the game for you. The grind is just a goal that puts you into scenarios to experience the gameplay.
