Playing a Gith right now feels very off IMO. Particularly with Lae'zel in the party the way npcs react strongly to her and hardly at all to you. Shadowheart in particular very quickly seems to forget about you being a gith and laser focuses on Lae'zel for no particular reason instead. I was hoping that it would have a level of reactivity on par with drow, but it doesn't seem to be quite there (yet, hopefully there is more to it in the full release). Seems to me the best way to play Gith in the full game is going to be to play as Lae'zel instead of a custom pc.
