any good faction servers

Tbh , the concept of factions is not very good for long lasting servers, as wipes must happen constantly to stop the ruining of entire worlds, since faction claiming and mass obsidian builds kinda results in un-raidable strongholds where sweat clans and sweep up the server, all you need is a smaller obsidian build, and an auto click/obsidian gen, correct? (don't think obsidian gens happen XD )
