I saw people spamming at Revenant's Toll for Chimera and CM runs for the whole 12 hours I played yesterday. Take the Initiative to join FC, Linkshell, or groups by socially interacting with others instead of letting duty finder do it for you. It took me from 5-15 min to find 3 HM Titan runs and 2 AK groups each. Never cool to generalize problems in titles like "Siren server is dead" if you have not tried all the possible solutions.
