How one manages their ammo economy is one of the foundational pillars of skill in Destiny. I'd much prefer our weapons did more DPS with significantly less ammo in reserve.

I’d rather have ammo be a thing.

Except even before that primaries were doing horrible in fact they were doing WORSE. Before we got the primary overhaul where like every primary got a 20-40% buff most needed a 1-2 full clips to kill 1 enemy and if they were shielded well good luck even with a matching element it could still take like 10 extra shots. In Shadowkeep there wasn't even a reason to run a primary except for pvp. Edit: Also a hand cannon and pulse can shred reds and deal decently against majors in even the hardest content but everything else (Except sidearms but nobody wants to deal with sidearm range) is basically not worth using.
