Robert MMORPG: Can we see inconsequential monster encounters have battle time reduced?

Yoshida: We do believe with 3.x that some regular field battles were a little longer than usual so with 4.0 they’ll be shorter.

So pretty much if you wanted a harder fight or at least make the world seem dangerous, don't expect that soon, mobs will die just like AAR health style, die in 2-3 hits leaving you with pretty much 95% health. SIGH.

I want the field open world monsters to be MORE of a danger, not a fly buzzing around you.
