Mastery Rank has helped me to explore Vanadiel
I just wanted to say that the addition of Mastery Rank has made me feel like I should go back to other areas of Vanadiel and try parts of FFXI, I would have never tried otherwise.
I really enjoyed all of the Windurst WoTG storyline and so many of the quest NPC interactions in Kazham.
I have been work towards Abyssea's Atma of the Savior to increase my master rank further (currently Rank 7).
Also, I entered monstrosity for the first time today and got my rabbit up to level 35. The XP campaign that started today this fun and enjoyable and makes me want to try to unlock other monsters. I absolutely love the mix of job abilities and monster abilities. The monster abilities have various TP costs, which is different from player weaponskills that require 1000 TP (However, I must say that I am upset that there is no Monstrosity connection to Beastmaster).
I also started evolving the monsters in my Mog Garden. I've had Rank 7 Monster Rearing for years, but I just got my first evolution from Wyvern to Abyssal Wyrm. (Again, there really should be a Beastmaster connection to these in game events!). I think the Mementos are a great way to add variety to my character configuration! I do wish the stats on Mementos were stronger.
So, I think that Mastery Rank gear is a great incentive. Please continue to reward players for playing FFXI and seeing everything it has to offer. (But please, do not neglect Beastmaster, Monstrosity and all of the unique characterists of Vanadiel that keep us connected).
Thanks!
