First of all, I'm not entirely sure if it's a bug or a nerf, but I'll assume the former. When the new helminth segment arrived with the recent updates, I decided to get it, and since I wasn't even on lvl5 with the Entrati, it took me a while to get there. And boy, it really took me a while. Why? Because enemy spawns are so bad it takes a lot of time to finish some bounty segments. One such mission is the competition with the grineer team: the pods spawn very slowly, only in a group of 3 (I was playing solo, so idk how it is for the group) and don't even guarantee to spawn an enemy when they burst! That wasn't an issue before at all, and the spawns were fine for the most of the Deimos' history. What happened, DE? That reminded of plains of the eidolon bounties where, while playing solo, you didn't get enough spawns to kill enough enemies in time for a bonus. I seriously doubt that DE will pay any attention to this issue, but still, it makes the gameplay very frustrating and tedious. Please, just increase the spawns both in vaults and in the open world, it shouldn't be too hard.
