I know we spend most of our time battling godlike beings nowadays, and heavy armor and magic-enhancing robes is fine enough for that, but I really wish we'd get some sets that reflected our actual profession as adventurers.

Something that would make sense for someone who spends most of their time exploring deep caves and huge mountains to wear, some of the gatherer sets are like this (the level 50 miner one is one of my favorites) but unfortunately we can't use them on combat classes most of the time...
