No I'm saying that in order to make jumping meaningful, a lot more work would have to go into it than creating an animation and allowing character to move vertically. It's one thing to add the feature, it's another to give it purpose.
I can't say that jumping is inherently "bad," that it somehow hinders the game or wouldn't have some place given proper supporting content. I must say though that by choosing to not include jumping, the game instantly took a stance on it. If you can't jump you build the areas with characters being firmly planted on the ground in mind. You create content focusing on other aspects of gameplay aside from area navigation. The game could certainly be reworked to accommodate jumping. It could be built up to provide an in-depth experience with that feature. At what point though are you moving away from what makes sense given what's already there and instead attempting to build an environment solely for a personally desired feature? At what point are you making a new game instead of improving an old one? Perhaps that last point is a bit exaggerated but I do wonder if jumping would truly make the game so much better.
I'm fine with jump if it's added somewhere down the line, as long as there's proper motivation to use it. Personally though I feel too much would need to be changed to accommodate it and what would be gained would hardly justify the effort. We can continue to go around the tree or tear it up and build a road. Either is fine, ultimately, it's just a matter of if saving time not going around the tree is worth the effort of destroying it. =/
Also, one thing to add. I know people saying jumping doesn't seem "FF" enough might get on your nerves. This is XIV and not XI, yeah. Thing is it's built by some of the same people and they set out to give us an experience different from that of the mainstream mmo. It may not be what you or any other person wants, but discrediting someone's argument because they feel that jumping doesn't feel completely in tune with the heart of the game is like saying people can't like other genres of games.
