So, from talking in the discord i found out bounties give exp too and not only loot.
This explains ( same experience of the person who brought it up in the first place in discord ) why i felt overlevelled after the first quest. I reached sacra, started taking bounties and levelled up like crazy. So, unless it gets reworked and revamped the amount you get etc i would personally suggest to just remove the exp. Maybe increase loot to balance it out. But we do get exp from killing monsters and from actual quests. we risk getting overlevveled fast.
The devs have already said that they plan to do it.
By the way, it doesn’t seem like this discussion has already been done on the forum, I think you’re the first to report it but ironically the devs figured it out on their own xD. You are spot on xD!
Since you’re interested in the same issues as me, how about taking a look at the topics I’ve written? Maybe you have something to say about them.
