Remove daily legendary drops cap

I’ve never played the Diablo 2 or 3 so idk how things worked in the past but as for now idk why they capping the legendary/set drops to 5 a day when you can’t sell them.

What’s the meaning of doing raids if you aimed goal is intentionally blocked by the developers?

A few days earlier I did more than 20 raids to gain 1 set piece till I quit and realized how things work and who knows how many people still don’t know.
