I remember one of the random effects of the trinkets was that it made all mobs within a certain radius attack you. (not sure if the trinket effect really worked though)
If that effect could be shoved into a food, I'm sure it could be useful to the adventurers whose role in group life is to take damage and leave the squishies of the group to deal out their spell damage on the mobs or heal group members.
The effect should override the current mob behaviour where mobs chase down the lowest ADV rating member of a group.
Limitations:
The effect does not work beyond a certain range. eg 40-70m (depending on the tier of the food)
The effect lasts 20 seconds or could be dependant on the tier of the food
The effect is tiered. ie if the tank is grouped, it should only work if all group members are within the current ADV rating tier of the "Bait Tank".
eg.
Bait Tank ADV rating - 38, lowest group member ADV rating - 26, mobs aggro on Bait Tank
Bait Tank ADV rating - 38, lowest group member ADV rating - 18, mobs aggro on group member with lowest ADV rating
...
...
Bait Tank ADV rating - 120 or higher, lowest group member ADV rating - 100, mobs aggro on Bait Tank
Bait Tank ADV rating - 120 or higher, lowest group member ADV rating - 99, mobs aggro on group member with lowest ADV rating
