I think it lies somewhere between PoE1 and PoE2 in pacing, though that strongly depend on build. I played few that was basically PoE1 cathegory "delete 2 screen worth of mobs at once" and one "basically facetank all but one or two bosses but it take ages" tanky. Though imo strongest part of LE which i already see PoE2 failed incredibly hard is game difficulty scaling. LE can be as hard as you want or are able to go, PoE2 makes you shit bricks in act one of story.
