Suggestion: Random Encounters

[Enthy]

I don't think I would like random encounter arenas. Though FFXI kind of did this with Chigoes (unable to target and very hard to see till they aggroed you) just no arena.

It would be an optional system, for example something you could trigger in the UI to enable random encounters.
Not just permenantly wandering the world you might randomly encounter a special monsters.

So it's S rank hunts with no fixed respawn timer.
And what you're talking about with class quests/story quests IS in the game already. They're called Guildhests. We just don't get any after lvl 40.

I'm guessing this is probably you're first final fantasy if you don't understand the concept just from the name alone. It's not similar to hunts.

Isn't this what treasure maps are for? You are digging and gathering and minding doing what you then bam here is the key to portal to where you can fight some dangerous monsters for loot. They called a treasure map and you can instance it at your leisure and you can even trade/sell the map. But if you did the map immediately and teleported to where it wanted you to go, it would be essentially this. Good luck if you meet a Chimera from peiste map.

Kinda hard to level via treasure maps. and Treasure map mobs are some of the most extremely unintellegent as AI goes.

Actually, I've played every single one of them except for 3, in addition to plethoras of others that run on the mechanic you're talking about.
However, the concept doesn't work the same in an open world game or just MMOs in general, so I am trying to reason what you want MECHANICALLY. The screen flashing randomly and loading a special area where you fight things will never EVER happen.
It would strain the servers because of loading new areas, it would break immersion, and it's more trouble than just spawning some mobs to kill.
The old method of random encounter was, as mentioned, a mask because integrating the battle and exploration systems was a pain or impossible with the hardware they had at the time.
