I wouldn't scrap it when chocobos and airships are added, and even if this suggestion is implemented.

Having a lot of ways to move around the game is fun.

Example: I am my Paladin in FFXI (T.T I miss my Paladin) I am stranded in the middle of Cape Terrigan, and I am needed in Jeuno.
1. Use a warp cudgel back to White gate and use warp taru.
2. If warp cudgel is unavaible. Could use my Tavnazian ring, end in Tav and change to Black Mage and warp back to Whitegate and use the warp taru.
3. Use Field of Valor to warp me back to my nation and airship to Jeuno.
4. Use Field of Valor to warp to home naton and outpost warp to Qufim.
5. Death Warp.
6. Pray to the goddess there is a black mage in the area with warp II.
