Okay, I'm currently in love with the class challenges, and I'm just wondering which class challenge people liked the most. You'll just have to vote for one of the trees, because I can't put down each individual challenge. Judge it however you like, gameplay, story, bosses, etc. and please explain your reasoning! You may pick your top 5, because it's really hard to pick just one!
I would pick Warlord gold (Love the extra challenge), Fighter Gold (Fast refreshing break from normal play), Thief Silver (Hard, forces you to squeeze out every resource), Paladin Gold (It makes me feel like the number one DD player in the world for finishing it ), and Wizard Gold (Always a fan of nostalgia).
