I'm guessing you are on a second class because I'm a returning player at 32 in MSQ and I know I am going to need to drop back and level a second class already or waste a lot of exper going forward. I expect to be 52 or 53 before I even touch HW content and with MSQ, map unlock and the tuning, exploration content I will put Whm at 60 long before I am done.
Note: Map Unlock is HUGE exper. Or it was in ARR. Each time you `discover a new area`it`s a flat number according to level but when the entire zone is cleared it`s a 10X on that. It`s all scaled to level so a 59 character who held a portion of the map unexplored in each zone can then go through and get the area compiled bonus, wiping out most of the last level in short time. You do need to plan well in advance though.
