That big experience bonus made a lot of sense in a world where you're talking potentially 100 hours to level up, or a large chunk of time to level; that big bump was something that we felt made a lot of sense. But in a world where our goal for leveling form 1-50 is much, much smaller, closer to 10-20 hours for people who are experienced with the game, or will find ways to do it even faster! We definitely know that part of what makes those heirlooms feel exciting and interesting was that unique experience bonus, so we do want to add something to replace that which will hopefully be equally as beneficial or feel unique and interesting for your level up experience, but not necessarily "here's a bunch of extra experience gain".
