Swtor was taking a HUGE hit of WoW clients, but for some reason Swtor starting to lose a lot of people. Then WoW started their comeback res scrolls to give people the chance to come back to the game for next to nothing . . . THEN if you subscribed for an annual pass (paid monthly, bi-monthly, or every 3 months) you got diablo III for Free and a new mount.
But yes, I miss the days of spending HOURS trying to down 1 boss in Molten Core . . . or having to craft all the gear to be able to not burn up in Black-wing Lair (I still sport my Onyxia Cloak that I made with my hunter pre-bc). That was the days of wow, but now few people will keep a toon at 60 and commit to pre-bc content. I do admit though, the new instances / heroics are a joke . . . I've died once in the process of leveling from 80-85 in the instances which is sad. . .
And I'd do private servers if my raiding buddies would join them!
