Do You Feel Uprisings are Worth Doing?
Short and simple answer would be no - they feel disconnected from the story and while they are good fun for when you just want to carve through waves of enemies, they just feel empty story-wise when even with the flashpoints that are given at the holo terminals by Malgus are given backstory before even stepping foot into them.
Personally, running through uprisings at the moment (haven't been able to test PTS because of it not being available to Steam just yet, downloading the legacy client as I type) feels exceptionally easy.
Most Hated
Personaly, I agree with the above, Destroyer of Worlds is just slow to do purely because of having to babysit a droid. Feels like playing TF2.
Next up, is definitely Inferno. Lord Wrad on MM is a pain in the arse and requires a certain healer that can do mass cleanses which not all classes can do (at least in my past experiences)
