If you rank them player-based it should be sth like
1. YoloRohan
2. AsylumRohan
3. B.W.G Rohan
Though if you wanna rank them as quality, I'll let you decide that by yourself.
P.S : YoloRohan is easy server, Asylum & BWG are a little harder
, though all three servers have put hard work and are worth trying.
