Avoid joining any Discord Communities in this regard, You should take any bonus gear that you want as long as it's a higher level you should be at an advantage.

You want to avoid Skill-Speed all together with Dragoon, the Reason being is that the class doesn't have enough Damage over time abilities and has so many OGCD's you run into an issue with desyncing and clipping in the rotation and clipping an OGCD or GCD with one is a damage Decrease.

Here is the Ideal Prority of Stats.
Weapon Damage > Strength > Critical > Direct-hit > Determination > Skill-Speed.

DRG Stat Weights :

CRIT = 1.0686 (1.0485 at 380 scaling to 1.0686 at 2500 and above, meaning have no Crit, or stack it if you have any unfortunately)
DH = 1.06225
DET = 1.06
