I found a temporary solution that works.
Setup a macro in wow like this
/use Abyssal Gulper Eel Bait
/use Blackwater Whiptail Bait
/use Blind Lake Sturgeon Bait
/use Fat Sleeper Bait
/use Fire Ammonite Bait
/use Jawless Skulker Bait
/use Sea Scorpion Bait
Then, in wrobot, setup your macro to run every 5 minutes.
What this will do is use Abyssal Gulper Eel Bait, then it will reuse the Abyssal Gulper Eel Bait if there's one in inventory or go onto to the Blackwater Whiptail Bait. Ran this for about 3 hours last night and only ever made it to the 4th item on the list. Prioritize what item you want by putting them higher on the list.
Why do I do this? I have an older pc that lags a lot in WoD so I fish from my garrison. Having the bot constantly change temp lures allows me to catch more than crescent fish and scorpions.
