I am not sure how long the update has been out... but in regards to Pablobobchann, I can vouch for many of the runs she did. I ran with her many times, and I never saw an xp elixer.

As Pab is a friend, and officer in my guild, I also tell you she has been on at least 12 hours a day. I would probably put that number closer to 16/day, but I can't say.

Regarding a plat/no plat leaderboard, I don't see it happening. As mentioned above, splitting leaderboards will alienate plat and no-plat users. A good alternative might be a time spent in game to achieve level cap leaderboard, but I don't know.
