Hi
I found IMO very good video guide how to (or more specifically where to)) farm Pools of Reflection.
Pools of Reflection Guide - Diablo III - YouTube
I have found this very useful when you trying to optimize your XP in end game.
Ofc you should not die or it is useless to farm pools.
And btw, here's a pro tip for those who are pushing and dying during Grift:
Open cow level and find the two pools, but do not claim them.
Run the Grift and upgrade your gems.
Return to town and go to cow level and claim the two pools.
Close the rift and enjoy your XP gain.
Here's short transcript of the video:
