Dual Keeper Aura HP/Nano
I noticed this the other night playing as a keeper. In a mission, I had my nano aura running. I started running into mobs that were a little tougher than I expected so turned off my nano point aura nano and turned on my hp aura. Those familiar with keepers know that thee two nanos are in the same line so you can't have both running simultaneously.
What I noticed however was that not only did I continue to get nano points (complete with messages telling me so) after I terminated the nano aura, I continued to get nano even after I cast my HP aura.
It stayed until I zoned.
I've repeated this on multiple occasions and it's worked every time so far.
Thus, if you terminate a nano point aura nano, and then run an hp aura nano you only have to use the NCU only for the hp aura nano but you get the benefit of both until you zone.
