I am almost level 1200, VIP 6, DK armor, guild level gives 50% xp bonus.
My brother is level 500, celestial, no VIP, guild bonus… laughable.
Completing a Challenge at Warlord IV gives the exact same XP both accounts. VIP bonus says * for gold and souls in specific battles but not Challenges, or XP itself.
So if the bonuses from armor and VIP and guild level aren’t counted in Challenge, needs to be clarified, or fixed. People should know what they are or aren’t paying for in the freemium bonuses.
