Matching Set Bonus's

[Soukyuu]

I like it when everyone looks different.

They do? All I see nowadays is
a) AF
b) darklight
c) GC set
d) whatever is deemed "best" gear to meld stuff to for that particular class.

It's only 4 sets of armor even though we have so many more. For example, I like the look of bone armors, but I can't wear them on my drg/pld/war cause of lolDefense/stats.

Yes, I still run into someone wearing something purely for visuals, but that's a very small minority. Vanity slots would solve that, so you don't have to choose between looking different or being "properly geared"
