After playing a number of matches once the changes were implemented i can say that i was right in my suspicions. There are no really viable checks to it at present (don't give me some bullshit about pinsir being a counter). The fact that i am forced to run a poke - NPdoom -specifically designed to combat it is a testament to its influence on the current UU landscape. Even that is not sufficient as every team i've seen also carries a chansey for this very reason. Teams that I previously could rip through 4-0 now take me to 1-0 or worse, thanks to Dual Screen and lunar dance. Trust me, theres nothing better than to see a chansey on 8% restore all its hp and pp for softboiled.
You only need to look at how it fares against the most powerful physical and special pokemon to gauge just how broken it is.
Su(b)perior (Megahorn) v DS Cress: 45.5% - 53.6% with NO SCREENS UP
23% - 27% w/ screens
LO Alakazam (Signal Beam) v DS Cress: 38.3% - 45% with NO SCREENS UP
18.9% - 22.5% w/ screens
Is it broken defensively? yes
Is it broken as support? yes
Is it broken offensively? can be due to its high defenses, Screens and access to charge beam
P.S. Calm mind makes it inpregnable on both offensive and defensive sides
The elusive triple threat suspect. If its not banned next time around, i'll be very, very surprised. Really, if it could fuck off tomorrow that'd be great.
