Situation Jump is and always has been a terrible idea. Every implementation of it in any Final Fantasy has been a mediocre attempt to give depth to the rapid decline in open world areas. Only a real time press to activate Jump option is by any means viable. The key will be in the Animation, the Hang-time and the stall. If our characters flail around like morons, wow style, it will be the literal end of the Final Fantasy realism style game play. If however, they incorporate a simple animation with a moderate hang-time and a fairly long stall we will have a completely reasonable mechanic that adds far more realism than it detracts.
