Okay here is the thing.

I believe the area we are in may not be the entire ACT 1 area, and if it is then there are some fights that are obviously set up for higher level adventurers. We may be higher level when we actually would normally get that encounter.

This area may change a bit at launch and the companions we find here may not be the ones that are in the EA. We know that they included the companions they did so that evil playthroughs (which they requested) would be more viable. You may not meet Lae'Zel until later in the game, and end up coming back here for her quest at a higher level.
