Dragoon has both the ‘‘Use One-Handed Spears’’ and ‘‘Use Two-Handed Spears’’ atributes, which much how like Doppelsoeldner has the ‘‘Use Two-Handed Swords’’ atribute is simply a way to give playes that take the class without taking any class that has said atributes beforehand to be able to use the class as intended regardless.
It was never mentioned that Dragoon would never be able to use skills mounted, it was also an event that happened in the KTest server, which in multiple ocasions including when the Rank7 classes where added recieved skills and classes that where still unfinished.
Hoplite is clearly made as a class for consistency as can be seen in Finestra offering a big boost to crit rate, to make up for it’s lack of spameable skills like most other Swordsman branches, and block rate which increases their durability as far as they are capable of blocking. It also counts with skills such as Sinchro Thusting which is meant to give you an incentive for you to keep using a shield on top of the block rate.
Hoplite pushes high burst damage in long cooldowns while being able to stay there and last for the duration of said cooldowns and it shows in it’s skill set.
Dragoon solely pushes damage, which has in common with Cataphract’s hability to enter the heat of battle to dish out high damage and get out to safety thanks to it’s mobility making for a good sinergy with Dragoon’s high damage and multi-hit.
And even then, what denies that Lancer is going to have the ‘‘Use Two.Handed Spears’’ attribute?
We simply don’t know.
