Well, I pre-ordered to have the 12x XP and level up 5 toons from 1 to 55. On the day SoR went live I sunk about 1 million creds on ability training -- but I also got quite a fat loot on the Rishi chests.
So yeah, all things considered, I'm very glad this will happen, even if my Legacy could be about 1 million credits richer.
