Loot Scarcity

Overall, I’m finding loot drop rates in DF to be pretty good - with weekly quests, sparks of ingenuity, vault etc. However, I’ve noticed that actual loot from instance content is few and far between (if you are unlucky). Last week I did a few M+ and 4 Vault bosses and didn’t get anything dropped. This isn’t a HUGE problem for me as other systems in the game make loot a pretty fair system but it sort of dampens the experience for me. There is something exciting about getting an immediate upgrade after a challenging keystone or boss fight. Thoughts?
