GW2 weapon system is built completely different than ffxiv job system. In ffxiv everything is bundled with your job crystal/weapon with no room for customization, save for minor stat changes. In GW2 you instead have weapons, passives and skills that complement each other and can be shuffled around at will (with some restrictions due to elite specialisation and skill types).

Though would not have minded it if they gave us more linked classes such as arcanist with summoner/scholar. Have always wanted to play an "inquisitor" using conjuration to smite foes.
