I found the options pretty good myself. I do wish we could argue back against Lae'zel though. Our character seems older given they've been to the Githyanki capital and she's never been to the astral realm before, yet she starts talking about this "Purification protocol" our character has never heard of and we just go along with it?
No. Githyanki would argue. And be paranoid as Hell about a protocol they've never heard of. I get that they probably didn't want to tip-off the Gith player too much about further spoilers but it is always kind of annoying.
Beyond that though we have some great Gith dialogue. I enjoyed making that one tiefling kneel for Lae'zel and talking about eating cats with the couple. I also liked that we get two different Githyanki dialogue with the old woman who offers gruel so we can be a snooty Gith or an adventurous Gith depending on choice.
Unfortunately for Shadowheart she has a nasty habit of running her mouth and dying for it whenever I play one.
