Apoxic: I don't pay 100% attention to the spread of it - but I've noticed that when I'm low on mana, the time on replenishment gets refreshed, so I'd assume it's not smart enough to "spread the love" and just repops it on the top 10 (or low 10..) mana users.

As a side note: SV hunters get shafted on replenishment - 5 points to max it out? I haven't looked into the specifics, but assumedly you could spec only say 1-2 points and still have it up most of the time? With high enough crit..

Ryan:

That is exactly what I do, and most do. All 5 points is a waste, 2-3 points, depending on crit rate, is plenty. As SV is a very crit-happy spec to begin with, even with 2 points you are getting an 80-90% uptime, and with 3 it's just never not up after the first few seconds of a fight.

It just applies itself to the lowest 10 people, if they already have the buff it just refreshes it (range withstanding).

If the leaked patch notes where you can dual-spec at any time when your out of combat are actually going to occur, they make this sort of thing look stupid.

Respecing for each encounter seems really dumb gaming wise.
