A few suggestions..

As if this game doesn't already have enough content lmao, but it's worth a shot in trying.

- If Ixion wouldn't spawn 3-4 in the morning.

- Raising the obtainment of Mendacity and Centurio Seals, as well as Beast Tribe currency.

- Quests could give higher Gil if you ask me.

- Eurika could use a bit more EXP bonus.

- More FATEs like Ixion added? More Wondorous items?

- Primals could have their own gear sets as well to go with their weapons? Would LOVE to have Shivas. Maybe even primals "gifts/wondorous items" as well. But only obtainable through EX mode?

- MORE REGULAR CLOTHING!! Most love to make unique outfits that don't have to do with war gear.

Thank you for viewing! If you did..:D

I have some suggestions too (sorry for my english btw).
MY husband and i bought the game 2 months ago (even Stormblood) and we couldn´t reach Stm because we are both DPS and the queues to do the dungeons and trials of the main story quests are awfully long....more than 45 min- 1 hour waiting (level 60 ones). I can´t unsderstand why such an awesome game like this one forces us to do this dungeons to be able to access the new maps. We decided to leave the game for now because we don´t have to much time to play and the time we log in we just queue.
Thats all, thanks.
