wanted to ask what is up with the random equipemnt, what decides what you get?. ive got almost every frame and every weapon in my inventory (cuz i just didnt bother deleting them after farming for mastery points) and i ive only made builds on a handfull of weapons and most frames that i use. making loadouts for all my weapons is just going to take too long so i was wondering how does the random equipment options work, if i deleted all the weapons and frames that i dont use will i start to get my items that i actually use?
