So I was thinking, why doesn't SE add a way to store EXP and give it to other jobs/classes the player has to help level? I think this would go really well with SE's promise to add EXP to the level 50 dungeons (which I think they said we were getting in 3.1) and help with the annoyance of accidentally of completing your Challenge Logs while doing end game grinds like EX Roulette and Alexander.
It could work like this:
In order unlock the EXP Bank you would need to first do a quest that unlocks when you get your first class/job to level 50 or when you bet ARR's 2.0 MSQ(probably in Mor Dhona or something).
They you can set it to save the EXP you gain via certain scenarios: Quests, FATEs, Leves, Duty Finder, Challenges,
Then, like when you withdraw gil from your retainer(s), you can select an amount of EXP to give to give to the class/job you are currently playing as. It would only go one-way, with no "refunds" for EXP used.
Players can only "withdraw" a certain amount of EXP depending on their level: Levels 1-49 can withdraw EXP equal to half the amount of total amount of EXP need to level up that level, while levels 50-59 can only withdraw a third of the EXP needed to level up.
For example, a level 1 Gladiator/Paladin can only withdraw 150 EXP from the bank until their next level up, while at level 30, they can only can withdraw 81,250. At 55, they can only withdraw 739,200 EXP.
You would have three types of EXP storage, Battle EXP, Crafting EXP, and Gathering EXP. You can only use the correct EXP stored on the correct classes.
For example, a Blacksmith and Alchemist can only get EXP from the Crafting EXP bank, but a Conjurer/White Mage can't, they would have to get EXP from the Battle EXP Bank.
Each of the three EXP banks can only store 1 million EXP at time.
Additionally, there could also be a Universal EXP Bank that you can transfer EXP from the other banks into. EXP from this bank can be used on any class/job but once used, the player will be locked out of using it for 4 IRL hours. Additionally, the conversion system for putting EXP from the other banks is 2:1, e.i. only half the EXP put into the Universal EXP Bank is usable. with the remaining half lost. The Universal EXP bank can only hold 500,000 EXP.
I would also like to suggest that they add EXP to the current end game content now, instead of waiting for 4.0. That way, level 60 characters can grind for EXP while also grinding for tomes and gear in EX Roulette and Alexander. I also think this would really help those of us who are burnt out from grinding in the dungeons and FATEs and have been doing so since 2.0. >w>
