Guild Wars 2

So I bought the new shadow assassin costume from the gem store and then realized that you cant replace individual parts of the item set because its a “costume”. I’m just wondering why this costume system is doing this, why can’t we just buy the costume for gem and then have our own say in how we want to mix and match? Isn’t one big part of mmorpgs standing out and sort of being different from the rest of the crowd? Why implement the costume system in the first place? Did people beg for this to be included into the game?

On another note, is it just me or do the designers at GW2 really need to step up their game. A lot of the light armor gear looks horrible (especially the ones on the gem store) and medium armor sort of follows that train as well. It feels like all the love is going towards heavy armor and even at that sometimes they look ugly as hell. I can understand if low level gear looks bad, but when you get to end game wouldn’t it make sense to have good looking gear?
Don’t get me wrong, there area few OK looking armor sets out there but none of them really have that jaw drop effect where you think “I NEED that gear”
