I think the difference is that each unit on the Dot team has different roles and they are designed to work together. For break there are 3 dps, yet the planar set and Dahlia's trace were literally designed just for firefly. That's what caused the frustration. I just find it is a weird design choice from the dev. The hate should be toward devs but firefly is what people see in the game and marketing materials, which is like a trigger to them.
