Of course it's all a matter of taste, although I really don't understand the idea behind quite a lot of designs.
Yea, I have to agree. Something went horrible wrong in the design phases where someone decided "Let's have the medium armor be different sets of trench coats", to be honest, any medium armor person I see, I simply assume they are all using the same armor. There is very little to tell them apart besides the color they are using.
Oh and maybe the strange western/cowboy hat thing they have going on too. I can't even understand why there is so little variety behind the medium armor selection. The only thing I can think how it fits a theme is for the engineers, as engineers have so many gadgets they need big ol' trenchcoats to shove all of their grenades and spanners in.
If you're an engineer, I think the vigil looks nice. Doesnt really fot with a bow or daggers, ect if you're a thief or ranger.
That's another armor issue that's been bugging me to no end: armor/weapon combinations.
There are hardly any armors for my female sylvari caster that don't completely "eat up" most of her weapons. I'm not talking about minor clipping issues, I'm talking about weapons disappearing for 50 up to 90% in all the wide skirts. Dagger/horn/axe worn at the side? I might see a tiny bit of the pommel sticking out. Staff on the back? The bottom half completely dissapears into most skirts. When I crafted her level 80 rare armor (masquerade), I was going to take my time and just harvest some stuff I needed to upgrade to exotic (exalted), but upon seeing the awful, awful, awful clipping issues, I immediately went to the TP to buy the materials I still needed. I'd probably be sticking with exalted forever because of this issue, even if I did like some other armor set.
Unfortunately, this is one of the big complaints about GW2; armor design. Far too many sets look too similar. Long, flowing skirts/coats, skin tight pants (or hot pants if you're a female scholar), and full sleeves. A few sets like this is cool, but this describes like... 95% of them among all three types. It's especially noticeable if you wear medium armor. Hope you like trench coats, cuz that's most likely what you'll get.
I personally like the armor designs, but I can see the lack of variety that bugs other people. I hope ANet has taken this into consideration and will add some different sets as free content and not wait until an expansion.
