There have been many failed attempts of starting fresh new servers from people that formerly played on, or were actual staff for, RoR.
S
Secrets
can attest to this.
They all ended pretty much before they got started.
IF RoR character wiped and started fresh. You are talking about people's progress of 6+ years being wiped away.
No one would want to start over. I know I wouldnt.
All attempts ended in failure
WAR Apoc was made by the folks who originally swiped the codebase (Cegee, Genisaurus, few others I believe) and is the only one that actually remotely 'launched' and had its 180 pop taper to 40 in a week, then to maybe 5 online the week following. There was 6v6 teams scrimming for the first month, though, but no consistent RvR population.
Azarael (former dev, smart guy) tried to make Interbellum, which had some very different ideas but would've been at least a fair contender if he were to pull it off, but unfortunately he lost steam and never finished it after losing motivation when Apoc failed.
Those two projects' failures taught me to never underestimate how powerful sunk cost fallacy is in the games industry.
It's why people still exclusively play WoW Retail, and why people exclusively play EQ Live.
They built franchises with characters that people have had for decades. In RoR's case, it's been about 5 years, but that is 5 years they'd have to abandon for another game that may fail, and the thought of investing another 5 years into something they already spent 5 years on was not a wise decision for a majority of players.
A fresh start server would suffer the same fate, which is why it just hasn't been done.
