AlphaRO was named after our desire for a new beginning. Unfortunately it came a little prematurely due to leaked information, and ... get this.. we're still in developement stages xD But anyways yeah the name AlphaRO came from as stated above the desire to become something new. Start from the start, from 0 members and build something beautiful.
The subsections of AlphaRO, Delta, Epsilon and Omicron are simply reitterations of their placement in the greek alphabet as related to their rates. Alpha being first, Delta short after, low mid rate, Epsilon a higher Mid Rate then Omicron the high rate. =)
