Xero--Just to correct you, there isn't double XP in effect. We've boosted XP for the early levels of the game in a bid to help new players enjoy the game more, get invested and hopefully play for longer. I'm sure everyone will appreciate we want to make an effort to increase player population.
all the way to 45 is early levels?
lvl 45 could very well be considered early lvls especially for chapter 2 in the future
also it does take a significant exp stack of boosting just to notice a big difference.
double exp pot+ exp pot+ rested exp+ sub+ doubles
