I would say that the most important thing to be able to transfer between characters in the account is androids.
I mean for real, this is purely cosmetic. Anyway they give away a lot of them every event and eventually u get stacked with a lot of androids and many times you buy them for real money, like in the current event. Let us transfer them in the account, we have a lot of duplicates of the same androids. Its not like we're trading the heart, only the android itself.
I know this might not be the most popular discussion or most popular request, or is it even legit.
But still, i think many players will agree with me. A lot of time has been passed, and some of us really miss this class, and really interested about what would have been her 6th job.
More than that, many jett mains have quit the game, many were very upset about changing main, and some(like me) wanted to make a strong jett character on their account, maybe even main it.
What im suggesting, or really hope for, even if the chances are zero, or close to zero, is that maybe you could bring this class back? I believe all its database exists, and its more matter of time and will to fix all the bugs that this class had.
I know that might be a not so legit request to ask, but i really think you should consider bringing it back, cause it was one of the funnest classes in the game by far. And it had the craziest flash jump and mobility in the game.
