Guild Wars 2

What do you think guys to convince our great ArenaNet to make possible changing armor skins from any type to any class. I mean that we should be able to use heavy armor skins to our characters which are using only light armor. What do you think? Are you fond of that idea?

PS. My english is not so great so sorry in advance for that ^^
PS2. I’d love to see my Necro in Medium Arah set :P

I think i found solution, i was playing on custom maps where is a limit of 2 tiers per day from custom games.

THx for answer @jportell.2197 i just wrote this in the same time when i figured out.

Guys i got a problem.
Today i made 25% of Arah progression and i can’t progress further. Is there a limit per day? Second thing is can i progress another tier when i started another one? I changed to Balthazar and i see no progression after won rounds.
Do i need to complete story mode of Arah dungeon to continue progressing?

Thx for answers in advance
