I'd like to see classes with skills, like a rogue with a stealth mode, a healer to heal and buff, a warrior with a berserk mode, a hunter to tame pets and use them to their advantage. An alchemy system to create potions. A world boss that would appear only once a week and would have a very rare drop, like a flying mount. A gem system to create status-enhancing necklaces and rings. Dungeon boss drops to create sets, weapon enchantments. I hope to see something like that. (Sorry for my English, I don't speak very well.)
