So, with the new ways of making money through professions that people are figuring out, the demand for leyblood has risen greatly.
This spot just outside Azurewing Repose features a cave of endlessly respawning Flashwyrm that can practically be two-shot by any dps worth their salt. Every kill gives around 3 leyblood, and a single AoE will usually net you between 20 and 50 leyblood. The going price for it on my server is ~2g each, which means you're getting 100g per AoE you put down, or an easy 5k-10k an hour purely off of Leyblood. It goes faster if you have your bodyguard out or team up with a friend.
This could very easily be automated, even by an autoclicker or a macro keyboard. Have fun while it lasts
