So let me begin by saying armor knights have existed since FE1. Their purpose was to have high HP or defense to tank ridiculous amounts of damage. They have had access to generally lances/axes but sometimes have had swords or even bows ala FE3. Yet ever since FE 10 unless they are raised from the villager class or given a specific personal skill that helps reduce extra damage they feel useless to have. Ambush reinforcements are ever present in larger numbers than before and a lot of enemies like Saizo from Fates simply carry magic weapons on them making tanking with armor units pointless. They never get enough resistance to stop those or spells usually without talisman usage or reclass support. So even with the new "Break" system someone can still ignore a general with weapon advantage and probably double them enough to kill them because being slow isn't the problem. It's trying to face tank a fire ball or thoron.
Does anyone feel these classes should be scrapped and recreated from scratch in a new game? I have not had great luck with them and found that even the characters Louis and Jade lauded for being pretty good in this class still feel like trash to me unless reclassed. Both have now died and I've completely given up on the class as a result because my only remaining general option without reclass training may be... Saphir.
