# Make Subjobs Gain Experience
Not going to happen. The whole premise behind having to level any subjob as the main is to give the player familiarity with how it works, understanding how to utilize that job's abilities/spells. Now, if it was 1XP per every 50~100XP for a subjob, that may be fair, but even subjob XP= 1/10 main XP would be too much.
# Make a new client for FFXI
Probably the hardest thing to get. SE would need to give FFXI more resources to do an overhaul. Don't expect this unless FFXIV really tanks and SE realizes it should devote more resources to FFXI so that the total number of players/accounts for FFXI + FFXIV doesn't fall below the number of accounts FFXI had say at some point in 2009.
# After the level cap increase
-Try to refresh older events by changing rewards, and restriction etc.
With so much stuff at LV75 being designed without any kind of level cap lifting in mind, and so little stuff at LV76+ at present (Abyssea is a fraction of the stuff existing at LV75), letting much of the LV75 stuff obsolesce is a bad move.
# New Expansion
-if a new client is released a new expansion pack would certainly be welcomed and would be a great idea to add new things to the game.
This would finally give the game a sense of direction after 2 years of being fully adrift and something to look forward to. Abyssea, while nice, is "this thing on the side" with an unknown association to Vana'diel at this time. It just seems like a place created to host activities for LV76+ in the absence of some expansion. There needs to be an expansion in the Far ___ (South, West, East, North, take your pick) with new zones. This would give players a sense of confidence for the 1st time since 2008 that this game isn't going to be potentially abandoned a few months ahead from any given time, that the people at the helm have a direction & a destination to steer this ship (and that there are actually people at the helm).

Somewhere out there, there is a road with 2 signs on it. One says "No Trespassing". The sign right next to it says "FREE KITTENS".
