As was said before (many times), it varies a ton based on the activity and/or modifiers. My most basic layouts for non-raid activity are: No modifier: Fatebringer (legendary) Black Hammer Hezen Vengence Solar modifier: ((Genesis Chain~)) (adept) LDR-5001 (solar) Hezen Vengence Arc modifier: Fatebringer (adept) LDR-5001 (arc) Steel Oracle Z-11 (arc w/ cluster) Void modifier: Doom of Chelchis (adept) Eirene RR4 (void) Steel Oracle Z-11 (void w/ cluster) Clearly these load outs take time to acquire w duplicate weapons w decent rolls and a variety of burns. The hardest part about answering this question is the fact that you'll often want to switch a superior weapon out for another depending on the perks, such as bonus damage to (fill in the blank). My suggestion, find your single best build based on the weapons you currently have, regardless of circumstance. Then when you get new weapons, compare those with you best weapons and build a collection for each of the elementals. Don't overlook the importance of armor though, because you'll want a solid collection of armor pieces which also compliment the activity/modifiers (enemy, burns, health regeneration modifiers). Given that this post was in April, you've probably had just enough time to collect a decent arsenal in time for Destiny 2 to drop and start all over 😂.
