You should try the TechNode server.
It's run by AnodeCathode (who frequents this forum), it has a lot of mainstream mods in a hardcore style. The mod pack is TechNode on the ATLauncher.
Thanks! Sad thing is, theres no such modpack in ATlauncher itself, but its listed on their website + server is down.
Im really sad, cant play minecraft with mods, everything broken and offline
