Guild Wars 2

I really don’t know on what to use it. The armorset from the shrines don’t really appeal to me and the cultural weapons are a joke (rare, not exotic). Did I miss anything besides buying obsidian shards?

Mostly obsidian shards, unless you like the temple armor. Also there are plenty of items you can buy for karma to get the skins, not necessarily the stats. (For example, every race sells a unique skin set of weapons that anyone can buy).

Oh, and salvage kits. Lots and lots of salvage kits and gathering tools for karma.
