:sigh:
Ate an Heroic Otto's stone and only got +300,000 XP bonus for being a VIP.
Normally, VIPs get a +10% XP Bonus. If that were the case today, I should have only gotten 200,000 bonus XP.
The "additional +15% VIP XP" means I should have gotten 500,000 bonus XP (10% +15% = +25%, .25 x 2,000,000 = 500,000).
Conclusion: They made the TOTAL VIP bonus to XP +15% instead of 25% TOTAL.
Lesson: Yes, whoever implements these bonsues needs more training. Next time, I will wait a few days for someone to fix the inevitable error before I use an Otto's. Will submit a ticket.
