Boost was inevitable. I was just wondering when they were going to add it. IMO if they do it, it should just come once with the expansion and not buyable in unlimited quantities like in WoW or other games. They should also keep everything locked except the new expansion content so you still have to go back and unlock it later if you want to do roulettes. It just lets you do the new expansion stuff right away but previous content you still have to go unlock it the old way.
