I doubt he created Cabdru for the reasons you list. Chars evolve. As I said in my own goodbye, I didn't ever intend to hit 40 - Hunsobo was supposed to be a throwaway "help-out-Draktel-'cuz-he's-always-alone" char. We see how that worked out.

Also I happen to know that Nep held off playing Scion/Imperial chars when he had a little bit of urge to do so, simply because at the time, Hunsobo, Kharghurln, Waserax, Ktaar, Seriistian, Kanaev, Haratzi, and more were powerful.
