Hello.
I would like some feedback relating having fun gathering triple triad, and if my views are universal or not.
My experience, the current card gathering are meant as a way to not only introduce you to the different content, but also show mastery of it. However, some of this has not aged well, but could be hot fixed rather quickly. Overall I recommend lowering the level from mastery to introduction, and allow for more triple triad play instead.
RNG dungeon content:
Currently there are many many cards that can be gathered through dungeons and card challenges across the world. Some cards however are exclusively gathered from dungeons alone. Some even require RNG from the very hardest dungeons. This is especially difficult for older dungeons few do anymore (like shadowbringer savage).
Solution:
Create NPCs that can be played for these dungeon exclusive cards. These NPCs would be unlocked at the same time you unlock the normal version of said dungeon.
Beast tribes:
There are two that comes to mind, the moogle and dwarves. Both of these are crafting beast tribes which also requires you to have crafting at hand. Beast tribes are mostly a thing of the past, but still allow unlocking certain content like mounts, housing items or cards. The oldest tribes takes many months to unlock.
Solution:
Increase the reputation gained significantly. Alternatively allow for playing the NPC that unlocks at full beast reputation to be played at a much lower level.
Blue Mage:
Blue mage is a separate adventure open world exploration and skill replication.
Solution:
Add an new NPC you can play for all cards after unlocking the first skills through totems. Make the cards purchasable for gil at the old completion level.
Eureka:
A separate adventure allowing you to "start over" with your current character in a different world.
Solution:
Add an new NPC you can play for all cards after unlocking the second dungeon.
Bozjan:
A leveling zone. It was meant as a decent way to level solo, possible for dpses having a hard time getting queue content.
Solution:
Add an new NPC you can play for all cards after completing the first dungeon (the one currently only allowing 2 cards to be won). Make the cards purchasable for bozjan coins at the old completion level.
If all else fails:
A very quick way to fix this is by having all of these cards purchasable at the golden saucer or unlockable by playing games there.
