This thread has gotten...strange. Btw I find it ridiculous to compare WoW to Final Fantasy. The two are entirely different, from graphics to overall presentation. WoW's lets you jump off super high cliffs because its a cartoon. FFXIV is not a cartoon, but leans more towards realism. As a result, allowing you to jump off a high cliff would be highly immersion breaking, since it would not make any damn sense in that world. It's like Yoshi said, it would kill you.
