I have just found that Neriak appears to be the first server to completely unlock Frogloks for the entire server. If you go into Character Creation you can now create a Froglok and must select Neriak when you go to name it (all the others show "unavailable".)
Way to go Ascendance of Neriak!
--Edit--
I have finally found a write up on the Ascendance's conquest. You can read it
here
It appears on 6/1 that Guk has been the second Server to release Frogloks for their server.
On 6/2 I was surpised, happy, and over joyed to find that Befallen became the third Server to unlock Frogloks. As this is my play server and I am excited to see they were keeping up with the best of the best!
Congrats to all three servers! I won't be tracking any further I was only doing the first three.
