Armors/ weps/skins
Mix armor from different sets around and try to find a dye combination that’s different. That’s how I’m doing it on my main. I suggest you go to the Storage Closet in the Heart of the Mists and preview all of the sets and start mixing around parts that you like!
Though as to your opinion of there being a lax of armor., there actually a fair amount of sets, it’s just that some are more popular than others. Also, the game is only two months old, ArenaNet added tons of other sets when they releases expansions to the first Guild Wars game! No sweat!
