You can find some of the staff mentioning pathing
in this thread located within the Client Upgrade Discussion forum. The gist seems to be that it will be a possibility but that it is low on the "to-do" list for the client upgrade, unfortunately.
I also find it funny that many of us talk about the unrealistic aspect to mobs phasing through walls while overlooking the laughable and absurd concept of FD pulling in the first place. First off, what kind of foe or horde of foes would be dumb enough to believe a stranger had just died before their eyes without even being touched, then proceed to walk away as if nothing had happened? This becomes even more ridiculous when you consider that mobs can fall for the same old trick half a dozen times over the span of a minute while the splitter works his/her magic.
Fool a mob once, shame on the FDer. Fool a mob twice, shame on the mob. Fool a mob ten times in a row and still live to tell the tale, shame on a flawed game mechanic! :dance:
I remember hearing long ago that FD splitting (particularly as used by Monks) was not initially intended and began as a misuse or even abuse of the skill's mechanic, yet the practice became so entrenched among the playerbase that it was left undisturbed and later zones were even specifically designed by the developers with FD splitting in mind.
Really, the concept of splitting would have made a whole lot more sense lore-wise if the original developers had given the role either to Rogues (who could trick or otherwise lure enemies away from a pack and then hide Solid Snake style) or to Enchanters (who could exert a kind of "mind control" to dull the enemy's senses and draw them in alone). Perhaps this latter method explains why Pacify-type spells were spread rather generously over several classes, though they never gained the traction that good old FD splitting had; furthermore, they have been gutted by the SoD staff to have even more limited usefulness, so I suppose the silly FD mechanic is here to stay: "Come at me, bro! Aaahhh! Ya got me! JK, I'm still alive! Aaahhh!! This time you
really got me! Haha, fooled you!" :dumbsad:
