Funny thing is that I remember threat meters being a pretty important mod to have when I was raiding in WoW. Mind you, I only played from vanilla up to Cataclysm so I'm not familiar how much the mechanics have changed. But I would have thought that WoW's raiding community would at least be aware of threat management upon joining FFXIV. Having it be part of the game and not some add-on is a godsend.

Granted, WoW was full of idiots too. Can't say they'd be any different once they get here.
