Since Professions are here and they all have individual titles, I feel like the final tier should be more unique among the professions considering theres already a difference with the Legendary Bounty Hunter title, ill also be taking some inspiration from a previous suggestion I had about this
( Skill Milestones )
Master Cook > Master Chef
Master Potionmaker > Grand Alchemist
Master Jewelcrafter > Crown Jeweler
Master Fisher > Sovereign of Shoals
Legendary Bounty Hunter can stay the same
Master Treasure Hunter > Gilded Pathfinder (I couldn’t really think of anything else, feel free to reply with a better one)
