Well, it's partly that, and partly the (now) instant charge time and potential for, literally, over nine thousand damage. Well, holy Bracelet can potentially do over nine thousand damage, not sure about how powerful a heaven knight will be.
Holy Swordsman, so you know, is nerfed. It has Dark Sword, some of agrias's skills, some of mel's but it's not the "what the gay, this is so broken it's not even funny" class anymore, and its stats are a bit low. It's very versatile, but it's not very WTFPWN anymore.
