Two dungeons is enough, what's the point of making three that just turn into faceroll content?
More vanity is always nice so I'll agree with that, textures are bloat, unecessary and the game is beautiful as is. That would bea waste of resources to focus on making a game look pretty, just look how well it did for 1.0.
And honestly, the chocobo issue is simple. When you call a Chocobo, it has to be defined as a party member, but it's also defined as a pet/minion. This is done so you don't have a group of 8 players with 8 chocobos out for a total of 16 party members.
It's designed so that when you have a party of 8, you can only have a party of 8.
The issue with the coding however is Chocobo's are defined as a party party. This is where it gets a little ugly though. You can't make the assumption that when you DF with your chocobo out the only scenario you have is 1 person with their chocobo.
If it was just that, then they might be able to release it already. They would just need to code it where When you A player are with your A Chocobo you are considered a solo queue for the sake of DF.
Another potential idea however is giving the leader the power to checklist who to queue in a duty when companions are out. When you queue in this manner a pop-up would appear. The ones who are checked to go into Duty with the Leader would say "Do you wish to Enter DF with "player name" Yes/No?" and for those who weren't checked it would say "You have not been selected for Duty Finder, is this ok?" Yes/No.
This would prevent the risk of potential exploits that could occur if someone were to leave someone out of a Duty via Party Finder for some reason and might be the easiest implementation of it.
The checklist would only show party members and not companions and it would put a queue on those who are checked off ignoring all other members.
Heck, they could take it a step further and introduce the ability to toggle yourself for solo queue even if you are in a party. So that even if you are in a party doing FATE to kill time, you can still go into Duty Finder. It might be the best way to implement a system that ignores other members without having to get into the nitty gritty of the code to retag how a chocobo is Identified for the sake of Duty Finder.
