What is it that makes DD better? More damage or something else?
I'll never remake, there would be 0 entertainment value in doing the whole thing again sadly.
DD crit is only better dor single target kills. For mobbing katars is way better as the damage will be much higher.
The reason dd crit can potentially do more dmg than katars is because of the daggers. They have a bunch of slots compare to katars. You have essentially 4 slots available vs 1 or 2 on katars.
For skills katars is better because of RC. While DD crit can also RC they cant so as much dmg as we so because they need katar mastery and advance katar mastery which they dont have. They need double attack for those skills and, the whole reason of changing at 42 job is to prevent double attack, so you can see how their dmg will be lower.
I persobally prefer katars, and I can still use daggers just not the crit part. You will have very high damage still as a dagger gx.
You also have the option of going crit katar and Double attack dagger(hybrid).
GX is pretty awesome, lots of variations. DD crit is a specialized build for sure.
Some enjoy it but If I had to remake my GX I would still be going full katars with the option of double attack daggers.
