I remember when I was appropriate level at beginning of Act 2 of DOS2 and everyone else was complaining about xp nerf patch and I had no idea what they meant. They meant gaining xp from killing NPC, of which I done none, but I still obviously done every single legal quest and experience in Act 1. I think that can't be the case here, you simply reach level 4 way too quickly... and of course story rushing is a thing, but I feel you can't try to please everybody, why can't story rushers simply do some adventuring before Act 2?
