Highest XP?

Lert: It came with a few lines, not 'every new line'.   Such competitions are usually to try and encourage people to play the new line. This however is 'the Firefly line', the line people have been asking for for years, since before the game went live. I don't think there's going to be a lack of people playing this line. Ergo, from WG's POV no contest is necessary.
