After 3 days of playing, gaining xp means nothing. That means mission xp doesn’t matter. XP Curious don’t matter. +XP for quickplay doesn’t matter. A whole system that becomes irrelevant after mere hours.
Why not have a system that uses xp other than level 0-30?
The game could level weapons and reduce the crafting costs of that weapon as the weapon levels up? When you think about it, the more practical experience you have with a weapon type, the more efficient with materials you’d be when tempering it. Like a blacksmith.
