Uhmmm... I think we kind of already have a "future sense," but we as in every character and not just a specific class. It's called AoEs. They show you where the next hit will land so you can dodge.

They used to have more synergistic skills. It used to be that Arrow = Haste, Balance = +DPS, Bole = +Defence, Spear = +Critical Hit, Spire = reduced the costs of TP skills, and Ewer = reduced the costs of MP skills. There was also Time Dilation which extended the length of our card skills, Royal Road which allowed us to enhance them either length or potency wise or spread them out over an entire group with just the click of a button. We also had a stun, and a skill called "Disable" (that was removed either by SB or before SB I think) that decreased the next hit of the target's attack by a certain percentage, and... stuff.

But SE has decided that synergy and saboteur elements are too much of a pain to deal with, so they homogenised the healer classes into one big identity-less lump.
