The XP bonus found on Experience Elixirs, VIP bonuses, Guild Airship amenities and items now also increases the Commendation of Valor return found in End Reward lists.
So this statement made me excited to see.
I ran a quest with Ship +5, Greater Tome +10, VIP +10. This is a total bump of 25%. I ran an EE quest which used to return to me 35CoV, it returned now 39CoV.
The base statement from the release notes made me believe that perhaps Turbine wanted to reward VIP and encourage the sale of EXP Potions again...
...oh well, I guess not.
(If anyone knows exactly how it works now, I would be thrilled to know!)
