So u really think if they made "Monk or Dragoon" a tank more people will play it, lets say it gets the same armor as PLD/WAR, all combos stay the same except they increase enemity/debuff,all there buffs will be dmg mitigation buffs, and just throwing in flash for aoe enemity. than all of a sudden with got thousands of tanks? the truth of the matter is that this issue exist on every game. Tank/healers have great responsibility and poor performance/death will lead to party wipe, and most people simply do not want to deal with all the rage thrown at them.
