At least some players more familiar with DnD expressed worries over what seems like a high level campaign being set within levels 1-10+. There was also some complaining about using higher level enemies and nerfing them so they can be fought by level 1 party, and overall changes to bestiary - especially phase spiders have been criticised for having little to do with "phase spiders" from the tabletop version.
If I remember correctly, around EA launch, the discussions on this topic focused on which would have been the best/worst way of nerfing these supposedly too high level enemies by adding/decreasing their HP vs. their AC.
