[Question] Lootmaster etiquette sanity check

[san-toki]

There are 8 reclears and 8 coffers. One per player. Just how there are 8 chest pieces. Random weapons are a bonus. I see no problem with what happened.

This logic fundamentally makes no sense to me.

You have good RNG and get your BiS weapon early. Why does that entitle you to a second guaranteed weapon while everyone else only deserves one?
