Monster Mayhem +X% XP Update

HBFT: Our event engineers are investigating a technical issue where in-game event reward modifiers are rounding down to the nearest 10%.   This is currently affecting the following in-game missions: Mission: Rushing Down The Line from the On Track events Monster Mayhem's month-long increasing +XP boost  
What changes have been made as a result of this issue?
In the interest of providing our community with the best experience possible, our engineers have performed the following adjustments to this month's in-game events: Mission: Rushing Down The Line experience rewards have been increased from 25% to 30% Monster Mayhem +X% XP Boosts are now awarded as follows: Complete Mission: Daily Wins 1 time -> +10% XP for the rest of the month Complete Mission: Daily Wins 10 times -> +20% XP for the rest of the month Complete Mission: Daily Wins 20 times -> +30% XP for the rest of the month Complete Mission: Daily Wins 30 times -> +40% XP for the rest of the month Complete Mission: Daily Wins 40 times -> +50% XP for the rest of the month   All Monster Power missions, etc. have not been affected and will continue on their regular schedule.  We will update the news articles to reflect these improvements.  
What does this mean for me?
As a result of these changes, all players will have access to +XP Boosts almost a week earlier than they would have in the original Monster Mayhem event.  Additionally, players interested in our On Track events will receive more experience than they would have received with the original On Track event plan.
