My 3rd and final point is for the ffxiv store (credit to Xenosys Vex for some of these ideas)
Make non-consumables account wide. You have some mounts account wide why not make it standard for all mounts to be account wide?
To add onto that why not also make the clothes you can buy in the store be account wide? Close to 20 USD for some of these sets and people can only pick one character to have it? that is 40 USD for two characters if they want just to use one or two parts for some fun glamours. Why not just make items that are non consumable account wide (mounts, clothes, armor, accessories, chocobo barding, some housing items.) I think a lot of people would vastly prefer this standard if you so choose to adopt it. I would argue emotes should be account wide as well where as consumables or more things that are one-off should be just set to a specific character (Dyes, Eternal Bonds, Tales of Adventures, Fantasias)
The other idea I would like to add for the ffxiv store, give us more things to buy in it. Retool some animations already in the game, the faster sprint you can use in Crystaline Conflict would be so fun to set as my sprint for my DRK. You can have some of these be in game rewards to, and have some more fun ideas for the store to sell. You have a lot of options for this part of it. You can change the color of abilities, my DRK is pink, think of how cool it would be for me to have a pink ability set to use. If you don't like that you can add in more idle animations for people to buy and use, you can have a fun little animation that plays when people switch to another job (could be played on job stone change). You can give people different gathering node animations. Animations for you gatherers for getting them to max, and you could sell some in the store. Some animations for craters, I know some people must be bored of swishing things in a pan the same way. You could even let us set different animations for increasing progress, and increasing quality. You could even split it up further and let us have a different animation for when we are action on different conditions, think of that if we could set a kinda bumbling animation for handing poor condition and have a fantastic delicate animation for handling excellent conditions.
Quite honestly I agree with Xenosys Vex about what he has said about selling/providing alternate animations I think it would be fun and a good idea.
Thank you for taking a look at this post and I hope it prompted some ideas for you to implement.
