Armour is tied, so all armors of lvl 50 have the identical stats. Armour can be divided into three categories that are melee (mage), range (range). Tier50 armour, runes, batwings, and blue dhide. They all have the same stats. They are simply different classes. Someone who is able to range a man in rune will have exactly the same dps stats as someone meleeing mage. Many things were nerfed or buffed. Deadly red spiders racked up more than 200k xp/h with 90+ cmb stats.
It's been nerfed. You can't simply click atk and eat until die. Pking requires skill, timing, and accuracy. Also, it requires reflexes anticipation, strategy, and timing. A man in bronze that is skilled and knowledgeable could outdo the person who does not.
