Sorry, but I actually like the current mob behavior, and actually feel as if monsters some monsters defiantly could be a bit more cowardly.
"I spied you out of the corner of my eye, I MUST FIGHT YOU TO THE DEATH WITH NO REGARD FOR SELF PRESERVATION!"
Seriously. That gets old.
I like how the Squirrels and Marmots can run an cower from you. I like how Antilion's will back away from you to expose their hind end for a back-kick if you're not wise.
Or how Raptors use a tail swipe move instead of their breath if you try to sneak behind them.
I also like how aggressive monsters and players are, in fact, territorial, and if you decide to run, they eventually beleive you're not worth the chase, are return to their set territory.
But about this issue of not being dangerious to explore? Ever go down the wrong path in Gridania and be greeted by a pack of level 22 wolves? Or take a wrong turn into what you THOUGHT was a shortcut and instead get nommed on by a level 72 Drake?
The dangers are there. But staying on the beaten path keeps you safe, which, guess what? It makes sense!
Now one thing I can agree on is that monsters should have varying run speeds. Some monsters should be a bit faster and others, slower. I also agree that night time should have a ting of fear to it (Or excitement for those out to hunt nasty undead things.) But it should not break the over all feel of the game.
As stated many times before, this is not FFXI, this should never be FFXI. FFXI has it's own appeal, and from the look of it, it's own new content to consider. If that's the game you want to play, please go play it over there.
Each chapter in Final Fantasy has been a new world with it's own twists and imaginings of the tried and true systems. Even the Sequals have had enough variation to have the game stand on it's own mertis. FFXIV should be no different in that sense.
