Hello,
When we raided 25-mans we used WRM (Wow Raid Manager) and then we ditched any form of raid management when we went 10-man since it was not really required - now WRM seems to have died and I cannot find an updated version for WoD...
What systems can we use? I suggested ingame calendar but some people have some issues with it...
Allgenda is unfortunately clunky and unintuitive
Wow-raid.com seems pretty nice and intuitive but currently has some issues with verification of new players
Raidbuilder.com seems outdated
