I'm working on the insane title, and I would like to use Carbonite to search for Blood of Heroes at their spawn points in the Plaguelands.

I've been able to import the nodes for herb and mining locations and have loved using those to route a farming path, and I'm sure the same could be done with Blood of Heroes nodes.

I've looked up Blood of Heroes on wowhead, and someone has posted all the spawn points as well as instructions on how to import those into TomTom via the .lua file. How can I do the same for Carbonite using the list of lua-ready cords?

You could add them as a Favourite using /carb goto x,y but this would limit you to a set route between them.

What would make more sense is for the Carbonite team to add the option to gather Blood of Heroes using the same system employed for Herb/Ore gathering.

I'd suggest starting a new thread about it, as it's unlikely that Carbonite team members will look in this (tutorial) thread for new feature suggestions. :)

Well... Yes and no... Sort of...

You can push the Record button and use "/carb goto" to enter the locations... Sadly they are recorded as "Target 1st" locations... So you can't chain them for routing.

Is there any way to use a short LUA Skript to record locations into the current (or any specific) Favorite?

I'm using NotesUNeed (AddOn) to store textual data, you can also use it to run LUA Skripts manually, so if you can add locations via LUA this would be the easiest way I think.
