Smn Players with experience, how are the 6.1 changes? (Especially the CD 3.0 & potency changes)

CD & potency changes were just done, so Smn need to use less ruin 3 fillers, till next Bamamut / Phoenix is up?

Over all dps remains the same? Or is it a more afterall? (Not just due to less ruin 3 fillers?)

But Sm have a bit more movemt time, thanx to the CD changes on the instant casts?
