Only William Wallace can use the word freedom with a sense. Don't talk about freedom, we are not under an evil king.
If, from a point of view it can add contents, because you can add tactics (as I have already posted in page 9),
from another point of view it removes contents, because the world is not projected to skip "checkpoints", what you will able to do jumping (some quest).
For example, monsters do not fall off when targetted, and I will be able to apply this kind of glitch:
Hit a monster,
Wait until it's near,
jump the cliff,
hit,
wait until it's near,
jump.
fun, is it?
Of course this is advantage of ranged. melees will have to fight normally.
Monsters can be done able to cliff down a rock face. Ok, What about ranged monsters?
Do you prefer monsters fighting on a rock face? If you are a ranged, it's fine, but a melee?
What I'm trying to say is: with the feature "jump a fence" there will be a lot of problems to fix. However, something like FFX-2 or FF13 is more realistic.
