Since the only way to get XP is through daily quests now, how come some people are already level 81? I missed some quests after the update, but have been collecting every quest since then, and am only level 60. I don't see how the few days I skipped could amount to twice the XP. Is there some way to P2W experience?

Or are they people that were far behind on campaign, and are now always going to be ahead of players that maxed out before the update?
