There are two new XP pots in the store giving 30% XP for 3 or 6 hours.
My suggestion is: Make the old 20% ones upgradable via Turbine Points. Otherwise me (and i guess most other players who bunkered many 20% pots) will not buy alot of the 30% XP pots until we used most of our 20% XP pots.
This would be a win win solution as we get more XP and Turbine gets more money compared to the situation it is right now.
