I was just looking into Druddigon's UU analysis because I was amazed with the wallbreaking power of its CB set, and I found this in C&C:
Steel-types are good counters to Druddigon in general, but against the Choice Band set you definitely have to be wary of Earthquake. The Choice Band set can be predicted around though, as Outrage has the side effect of being locked into it and Earthquake can be sponged by a Levitating Pokemon.
I can't really remember when it was last updated, but Levitating Pokemon aren't really safe either. 252/252+ Bronzong is 2HKOed by Earthquake, and although others (except for Rotom-H) fare better, they shouldn't be switching into it expecting an Earthquake either way. Now if this was written before Mold Breaker came out, and then the sets were updated via SCMS with BW2, then it's ok, but that sentence is really misleading. It should be Flying-type Pokemon, and people need to be warned that CB Outrage hits them all really hard, so you need to predict carefully around it.
Also, I already said this to kokoloko but he's been busy so I can understand that this hasn't been corrected, but Slowbro only needs 12 SpA EVs to OHKO 252/0 Roserade after SR, so that could be changed in the analysis (I was the one to write it, but I based it off the previous one and didn't bother to do the calcs myself—sorry about that).
12 SpA Slowbro Psyshock vs. 252 HP / 0 Def Roserade: 284-336 (87.65 - 103.7%) -- guaranteed OHKO after Stealth Rock
