I tried running Unyielding Aura on my monk hero and noticed that, when a party member is dead and they discontinue the enchantment (so as to gain the rez), they don't take the new range limitation into account. It was nerfed so that the rez can only occur within normal spell casting range, but the heroes will still drop the enchant from much farther than that. It was, of course, no big deal how far they would drop it from when it had unlimited range, but now that it's limited, I think they should tweak the AI so they're at least smart enough to enter spell casting range before dropping it.
--------------------------
On a similar note, UA's rez has a second or two of delay between the time the enchant is dropped and when the rez occures. A hero who isn't having UA microed will drop it, enchant it again, and then immediately drop it again even if there's only one person in need of a rez. It would be nice if this was addressed too.
Lastly, (and this point is more a hitch in the functionality of the skill than a matter of the AI's use of it) when UA performs its rez, it seems to either cycle through the list of dead party members or select a dead party member randomly (I'm not sure which). But if the selected dead party member is not in range, no rez will occur, even if there's another dead party member who IS in range. I think this may be a second leftover from when its range was unlimited and just wasn't addressed when the range limit was imposed. I would like to see it fixed so that it will only attempt to target a corpse that's actually in range.
-----------------------
lol. Upon loggin in and reading the update notes I see they just fixed problem 3 directly and problem 2 indirectly by eliminating the rez delay. TY ANet.
Problem 1 on the list remains valid (I just tested it).
