Personally, I think it would be cool to have to get to level 75 without the epic buffs - a lot of us got to level 50 even without premium, and it was only once we reached that tier we started getting bored.
So for BB to introduce the extra levels only to have us buff kill our way through a lot of it seems pretty pointless IMHO. What will people do once they have reached Level 75 so fast? I'm guessing the forum will again be full of players complaining that the game has become stale and boring, as I previously have..
Whatever BB decide on this, I'm totally looking forward to all the new content as it's been a long time coming. This time though, I'm going to venture into it more slowly and enjoy it while I can
