I do. I'm wearing heroic AoC 2/2 (finally, don't get me started) so my Fire Elemental is on a 3.38 minute cooldown. I absolutely hold every other EM to match up with Fire Elemental Totem, unless the boss is going to die before FET is up or is doing to die in less than EM's duration.
Regarding Stormlash Totem, I use this macro to prevent overlaps with other shaman in my raid:
Code:
#showtooltip Stormlash Totem
/targetenemy [noexists][noharm]
/cleartarget [noharm]
/tar Stormlash Totem
/cast [harm]Stormlash Totem
/targetlasttarget [help]
If there's a friendly Stormlash up in range, it won't let me cast mine.

EM's cooldown is 90 seconds. With heroic AoC 2/2, my Fire Elemental cooldown is 202.8 seconds. So, holding every other EM to match up with FET loses 22.8 seconds every cooldown cycle.

EM Overlap (On CD) in a 600s fight.
EM(1): 20 seconds.
Total: 20 seconds in a sub-10 minute (600s) fight.
EM Overlap (Synch)
EM(1): 20 seconds.
EM(3): 20 seconds.
EM(5): 20 seconds.
Total: 60 seconds in a sub-10 minute (600s) fight.
To actually lose an EM, it takes quite a while. On the other hand, having a hasted Fire Elemental is a lot of damage. Hold it, IMO.
