Nothing should have changed on normal with the exception of the Optional Objective.
BTW.. the Optional Objective Loot bag never dropped Set Pieces... If that's what you think has changed. it only dropped random BOE stuff, Rare Salvage, and the occasional EDC (common salvage).
I think the optional objective is a slight bit to hard. After playing through a few times last night we could never keep the Kang's hull above 75%, we could keep it above 50% most of the time. One piece of feedback I would give, would be to lower the hull requirement on the Kang to 50%.
up until the patch yesterday 4 team members could work on the cubes, while one protected the kang. then when they got a cube they would help the hang, rinse and repeat and mission is completed.
Last night anytime I went to play it we would get one cube down then it would say optional objective failed. Then as we worked on the second cube it would say mission failed, leave map. maybe we'd get like 6 of the 8 spheres on the second before it stopped. I did this with several different groups. The Raptors also did feel a good amount stronger.
Maybe there was a ninja fix in the evening edition. I played Cure several times today and didnt have any problems, though the Autoteam bug seems to be back.
