Questions I cannot find answers for

Do ravens get their hits back when a druid gets healed? All one's other
minions are fully restored, but it seems to me my ravens disappear very
soon after I return to the fray if I don't renew them myself. 

Does bow speed make any difference if a merc is using the bow? I
*thought* it did, but someone insisted to me the other day that it makes
no difference on a merc. 

If I start a game with a character who has done a quest and play the
quest with a character who has not done the quest, I get the quest-drop
benefit without completing the quest. Does it work the other way around?
If I have done the quest, but start the game with a character who has
not done the quest and do it with the character who has done the quest
already, do I get the quest-drop benefit?

If two trains leave Tristram at 2:30, one traveling west at 45 mph....

Mark.

While I'll admit that anyone can make a mistake once, to go on making
the same lethal errors century after century seems to me nothing short
of deliberate.--V.
