I'm not sure what rebornbuddies stance is on this but the auto repair is considered a hack, and I think as with honorbuddy they like to make it as lifelike as possible. If your chat logs were checked and they saw you repair in the middle of the forest it would be the end of that.
I mean, no doubt it would be useful.. and no doubt it will pop up if thats the direction RB takes. Personally, things like that.. radar.. teleporting..speedhacking... are dirty and dont belong in ffxiv.
With that said i can think of about 10000000 other features the bot could use, but these things take time. A good communty behind the bot can help speed things up however... I'm feeling like a pretty big leech atm considering i cant code at all (time to start tbh)
This will be one of the first things that I do when the new NAV system gets released. Right now its not really going to work out unless you happen to be close to one.
