Dragon Knights can learn abilities such as maplestory powerleveling Dragon Roar in the third job, as well as Elemental Charges for Knights and Combo Attacks for Crusaders.
Due to the large damage to opponents at round level 50 and onwards, people make a decision to become Warriors. However, there are some social issues to warriors. For example, in "Kerning City PQ" for levels 21-30, warriors are looked at as being weak, and are usually not recruited into the party quest. Yet Spearmen are chosen at around level 40+ for Ludibrium PQ, for their ability to Hyper Body, which temporarily increases HP and MP for a whole maplestory powerleveling party. Pages are looked at as a minority. In case of Fighters, the special skills and Spearmen, they don't possess the raw power, required being a powerful character. This is why people choose not to become a page. Their only advantage are the powerful skills at around the third job advancement, but many Pages do not make it this far.
HP Warrior is another band of Warriors. Only do these Warriors increase their Hit Pints, not their Strength and Dexterity, which means that they have around 10,000 HP at level 30 and the job advancement. Due to the high of Strength and Dexterity, it can be very monotonous to get to level 30. If HP Warriors become Spearmen or Fighters, they possess a new skill called "Power Guard." This means that up to around 30% of damage dealt to the maplestory powerleveling warriors is returned to the monster that dealt it. Owing to the large amount of HP, this is a huge advantage which means that low level HP Warriors can take on monsters that are about level 70 to 120 around level 40. HP Warriors take far longer than any other job advancement to train and become strong, and that is why most people choose not to take this route.
