Please do not make group quest open world areas.

You are talking about one of the most Hardcore MMOs, and how they should fit those systems PRECISELY into what is in all honesty a pretty casual MMO. It's probably not going to work. And for a game like FFXIV, which has been adding tons of amazing dungeons and boss fights in the past two years, I wouldn't want them to waste too much time on random bosses on the world map that end up unbeatable or only something elite raiders can handle.

However, you've reminded me of my only beloved "dangerous world" moment in an mmo. The Fel Reaver, in Burning Crusade of Wow, was a giant world boss that stomped around the first zone, and pretty much instantly murdered anyone he stepped on. He didn't drop loot, didn't have a reward for killing him, and pretty much existed just to step on people who were too tunnelvisioned to notice a building sized robot slowly stomping toward them.

Are you even reading what i'm saying? I am asking for a few bosses like that and a lot of normal ones spread around with semi-random spawn places that wander around, deep inside territory so you can't just "know" when they are up less you fight to them! That is what i'm asking for, a few of them that can only be killed by the best players, whilst 90% of the rest can be killed by players.

5% Total Hardcore. (2x group encounters, to 4x group, locked.)
27% Hard, challenging, hard to kill. (1 group encounters, to 2 group encounters, locked.)
33% Easier, camped probably, but still random. (1 full group, locked)
33% Very easy, soloable even by good players! (1-3 people, locked.)

Wandering Bosses, they spawn in random (semi) locations and wander around the zone, they spawn mostly where no players are.
