SiimonHarm here.
I have been playing on this server for a while now. Some cranks here and there, servers sometimes crashes and quarry's stop because of that, have burned a lot of coal like that. But that's is I think the only downside of this server.
Overall, the server is really great. The community is awesome, would like to see staff on a lot more though, maybe they just don't like tekkit server. Ranks are fair and useful. Mods are well balanced.
I will be playing on the server for some time definitely. Come join us, we are glad to have new players!
