I think the encounter with the githyanki by the broken bridge should be tweaked a bit.
As it stands now it's really really hard to resolve it peacefully and fighting them could easily end with a TPK (I met them with a level 3 group and I was no match for them).
The only viable course of action if you can't beat them is to watch the cutscene and then avoid the encounter altogether, which makes no sense if you have Lae'zel in your group and you're actively looking for a creche.
