I've just hit level 20 (well, i'm above that now) and obviously have been given access to the subclass CO. I've managed to grind the Fodoran and Garongo and found 2 of the 5 Gilnas while finishing my desert missions. I've read that Gilnas are easier to find in the mines, and afaik they're only in the desert as a rare-ish encounter (level stats indicate they show up less than 1% of the time) Is it worth waiting until I unlock the mines to finish this CO or should I go wander around the desert for hours until I actually stumble across 3 of these things?
