Not true. With the Field of Valor Page 1 option netting people 1300 exp for 4 lizard kills (and 4 bunnies), the Lizards in Cape Terrigan are way overcamped that the possibility of getting more than 10 on a Firesday is unlikely. Using Attohwa Chasm seems better.
Kuftal Tunnel is also a good spot. Very lightly camped with a Lizard Room. I went from 110 to 83 soloing in one day.
