Best place to find them I found was the lake filled area east of Ashen Strand.
I eventually got it done after riding up and down the western shoreline between Zan'jir Terrace, Ashen Strand and Mezzamere.
For me, I got credit when I was the one targetted as it died, which might help if you're having problems with spawning the pools required.
