I know at one point that at least some totems pulsed on when they were dropped, so you could actually benefit from staggering them out. However, I thought I read some Blizz notes somewhere that suggested they were moving totems to use global pulse timers, so that all tremor totems pulsed at the same time, etc.

I'm not sure where I'd find that info again. Anyone else have anything that they can add here? It'd definitely be handy to get a solid answer.
