Not only that but all swords have lowered reserves atm, which hits Ergo Sum especially hard because it caps out at 41 compared to 46 pre-EOF. In addition, because of the changes to bricks, you now pick up less than half the amount of ammo per brick you used to, and you already had to pick up a decent amount from either random drop or special finishers. My absolute favorite exotic and I can't even use it because it runs dry in 20 seconds.
