I was wondering if you want to make a second job, is it better if you make a totally new character or use the same one ?

1. If you make the same, you can use the same tomes/phil/myth cap for your alt, while you earn them on your main. This will speed gearup of the alt.
2. If you make the same, you cannot join as PLD on coil for example and roll for WHM gear, so is not helping that way
3. If you make the same, you are saved in T4 coil, you cannot do T1 again with your WHM so you have to select if you wanna do this week coil with PLD or WHM.

So generally speaking, which one is better as idea ?
