After skimming over the thread, all I can say is that you rarely find them in raids for a combination of reasons.
- Finding a good player is rare for any class, especially ones that aren't entirely working.
- Even if a class is fixed it will take quite a while before the viability is widely known.
- The Warmane/Molten community is good at believing old news, real or not, and ignoring anything else.
- A good example would be the current state of resilience, as perceived by players.
- A lot of people choose a class based on how well they have seen it preform, so Rogues are Ferals continue to be rare.
- Just look at how popular Rets and Hunters have gotten.
PS: Combat Rogues bring an additional 4% physical damage buff to the raid, the only other way you'll see this buff is by bringing an Arms Warrior. You'd think Warriors in general would use Sunder Armor, but they don't, and Rogues *can* bring this as well. Ferals on the other hand have some nice buffs, but they're easily replaced by a bear (or an Arms Warrior, even though that would be even rarer) + a boomkin.
