There was an interesting post in the official forums where a player asked if the Pool of Reflection bonus(es) would carry over into Reaper of Souls once the expansion goes live.

My questions is kind of odd so I’ll try to explain it as best I can. Say for example I want to level my Demon Hunter first in ROS. So I am playing my Wizard and Barb currently while waiting for release. Everytime I get a Pool of Reflection I port to town (I’m playing with friends so it get’s saved) and log into my DH and snag the pool, logout and move back to my other character. Does anyone know if we will be able to “carry over” that experience to ACTUAL levels, not paragon in a week when ROS actually releases?
This is a very good question, and this is an even better answer…

In this example your Demon Hunter would have the Pool of Reflection bonus for Reaper of Souls. The buff is not intended to be removed when the expansion goes live. However, it should be noted that Pool of Reflection’s only stack 10 times. Here’s a bit of info about them from the 2.0.1 Patch Notes. (Source)
Given this confirmation, it’s safe to assume that we can go out and roll up 10 stacks of PoR bonus XP pools on our “main” – giving them a leveling advantage right out of the gate in Reaper of Souls. Now that we know the PoR bonuses will not be wiped once Reaper goes live, stacking these buffs will be an excellent strategy on the eve of release.
