Why use a Dragoon or Monk when you can use a Warrior?

[Aion]

There is not a warrior alive who can out dps my dragoon, against any number of enemies. There is not a warrior alive that can out dps a monk on a single target. My linkshell doesn't use warrior in any situation apart from tanking. Warriors replacing other classes? LOLurdoinitwrong.

since you good using DRG, I wanna ask some questions:
1. what is paralysis do?
2. What kind of damage can be reduced by dreadspike, is it all kind of damage?
3. I found vorpal thrust usually miss, is it by nature of LNC post 1.21?
