Personally, I only buy level boost with gold nowadays. I tried to level my rogue with the "new leveling experience" but almost all of the time I skipped it entirely and just jumped to a new character to level up. I bought character boost for a mage, a warrior, a paladin and a druid. Yes, they did to get moar money. Everyone saying they did it for funsies is just a fanboy of vanilla (or more likely TBC) leveling. PS. While I bought a leveling boost for these 4, my rogue is still level 59.... I honestly dont think I will continue.
