I like the following ideas:
Linkshell House - STO has done a FLeet HQ which you can build up and develop and even do missions etc together.
I like the idea of being able to get rewards together to build up a Linkshell fortress/House, which you could even use as a quest mission once a week - 6/12/18+ people have to defend it.
Similar to campaign but its your Linkshells customised fortress, again you could earn items which boost the fortress? I understand this would be a massive undertaking on SEs part to do it right and make it feel like new content not just a copy and paste from Campaign. The boost items could be simple stat boosts for all players, on the fortress, NPCs helping. When campaign came out it was fantastic, only real reason why its not heavily used now is EXP/Cru from Abyssea is what most people prefer. SE though had made massive changes though to improve.
Maybe even allow notes to be the points in boosting your fortress? (because I dont like the idea of yet another currency/point build system).
Tavnasia, I still think they are lacking this very original story area - allow us to visit the ruins which were destroyed in the great war. I miss beating up a bunch of orcs, maybe have simple rewards and again like Abyssea doesnt require a full alli or even a "certain" type of party. Not too sure but I like the idea of being able to visit the ruins, maybe even expand on the new tavnasia after all this time the place hasnt changed much ;)
Linkshell modifications
Some people like a few I know dont want to scrap the current LS for any old members to easily get back on but he leader has gone and wont return. Make it possible to vote a new leader of 75% of those recently on in the last month or so? or only for the LS's that the leader has been inactive for 1 month? 2 months?
Like XIV you can see a whole list etc
- I am guessing this is a huge task
Mog House
I think this is something they are doing? the ability to have 1 Mog house and not multiple in different cities. I just want to have 1 home and that I am able to access it etc I did have a bed and everything but gave up because I rarely visit the home city.
Trial List on the Menu
I know we have the ability to check with a fancy book but I do prefer a menu which shows:
Whole list of Trials and what they are.
The list of what you are currently doing and what is required.
Personally I see this one being the quick and easy one to setup, just requires some poor soul to sit there and do it. Although we can check Wiki etc I prefer this info to be there (its not like something you have to work out for your self).
Perhaps the same done for AF3 stuff (the moogle again tells us what we need so its not like its telling us cheats). Maybe even the ability to give the seals/+2 items and when you collected 10+ you can choose to spend 6/9 etc on a piece of gear. Saving me carrying 10 slots worth of +2s. Similar to the old Sea style where you simply collect the ancient coins, trade them to NPC and he stores them till you want to spend.
Obviously the ones I have added are my opinions, by all means do what you guys do best tear it apart or like it ;)
