Dyes would really be a great addition to the Inscriptions profession.
Inks that can be applied to armor. I have so many low-level inks that are just useless.

Armour dyes would rock, WAR implemented them and it really gives a sense of cohesion when you pick up a new piece of gear and know that it can look exactly the way you want them. It could give the scribes an extension to their profession too.

I do like the way WAR has trophies that you can attach to armour, another level of customisation that could be tied to achievements or epic rare drops. No boost to stats just a trophy for a job well done.

While I'm singing the improbable want song. How about an armour hall type affair in guild housing. Somewhere to hang that first set of tier armour with pride. As a BS I cried a little inside when my Imperial Plate went the way of the vendor. It was a long hard grind to get all that and to trash it was upsetting.

One last one now that we have instanced zones. How about breathing life back into Gnomeragan? Take one epic quest chain, a long hard grind and at the end of it you have a fledgling city that's rebuilding itself. It would breathe some action back into Azeroth and open the game up for extra expansions based on what is now a dead zone.

Armor dye?
Aka.. Guild Wars.
Yes, that would be nice.

I'd rather just have the armor designers from Guild Wars, at least they can expansion in expansion out make great looking armor.

Guild Wars? Ragnarok Online beat them to armor dyes by about 4 years.

Dark Ages of Camelot has had armor dyes from the beginning.

Ultima Online had armor dyes before DAoC...

And I assume the idea was in another game before that, and before that, and before that...

Everyone knows it's not a new idea, no one cares where exactly it originated.

And as we're tracking the history of armor dye, The Realm Online (initially by Sierra, then Codemasters, now Norseman Games) had it at least four years before Dark Age of Camelot...

Anyone think of an earlier example?

The DAoC/WAR dyes would be great and the trophies too. The problem is the Blizz art designers have an ego problem IMHO and don't think anyone should try to improve on their design. What I wouldn't give for armor that looked like armor instead of 5000 dragon nipples attached to TRON outfits.

But I WANT the Tron Plate Spaulders of the Many-Nippled Death Drake! QQ

Seriously speaking, armor dyes are a feature that I've been waiting for (hoping for) since before Burning Crusade. Dance Studios? Meh. I'll go if they put them in, I guess, but armor dyes come first for me. Northrend kinda made me forget their importance with it's "every damn piece of armor is exactly the same" look, but then I switched to leveling my DK up in Outland, and I remembered why I wanted them so much: If he walks into Silvermoon right now (which he won't, being a Tauren, I guess), then the Arcane Fashion Police will put out a warrant for his immediate execution. :-/
