Because Destiny 2 is a looter shooter where each weapon and armor piece can be rather unique, having desirable perks on each drop would be ideal, albeit making it too easy to obtain the best rolls possible would trivialize this part of the game. It's a tough balancing act when some of Destiny 2's available perks are subpar, as improving them means going through different iterations of the buffed versions and seeing what makes them good enough to compete with other options without being too strong. Recently, Bungie buffed Pulse Monitor for these reasons, and the new version of the perk is much better than before.
