Here i disagree ... You need characters of medium strength, when you are gathering telemetry to tune difficiulty of your encounters and skill rolls.
By stat rolling you can get lots of exceptionaly strong, or exceptionaly weak (yes i know, its unbelievable but people do this aswell) characters that would make quite a mess in your data. It maked perfect sense to only include point buy in EA ...
But now, when this part of the work is done ... there is no reason to not include it in Final Release!
It's the same problem, if you want to test things in an EA, you can test everything and not run into RFT issues later in the release due to having high stats. I sincerely believe that there is something that they do not want to say or that they are afraid that the game will break somewhere due to certain combos that they do not have planned and that is why they restrict things so much. And if people can make characters with vitiligo, scars or whatever to identify with themselves, I still need to identify with a warrior who is not only very strong but very charismatic and intelligent and I don't have enough stats to do it. :P Just joking, Im just strong and a silly one xD
