They just did again the whole, you're from that race but actually no.
It depends ...
What benefit tied to race you would expect?
I would expect special dialogue options, bonuses for some options, racial spells, stat bonuses, and possibly some racial-specific gear since the beginning.
And except the last one, everything is there.
Apart from some special dialogue lines, my Githyanki mage didn't feel different from any other race.
Except you can cast spells in Lae'zel armor ... cant you? O_o
Also, you can jump aproximately 3 times as far as usual mage ...
And i believe that when you get spellslot-free misty stepp on level 5, that would be also appreciated benefit.
I mean ...
What else did you expect?
