I hadn't looked too much into the dyes, but with the recent story up top, I decided to look at them a bit. I think it changes the armor enough to make them a cool idea.
Although, Flux (I think it was Flux...) made a good point in the article. Would you guys pay for DLC dyes that added cool effects to your armor? Similar to full IK armor or something? Another one that I think would be cool is having an armor color that has a smoke-like effect coming off it.
Another idea would have a customizable dye. You go onto the site and select the hue and values of the armor/smoke and then you can use that dye one time. Charge $20 for enough dye to do a full armor set. I'd buy the **** out of these.
They appear to have held back some colors. For instance, there is no black dye. The darkest dye (abyssal) is just a dark grey.
I'm not keen on all these fancy effects on armor dyes. I think just plain colors is a pretty good option already. There's only a few pieces of armor in the game that have any special effect/animation, and I think the WD has them all. I'd be happy if they kept it at that, and I don't see a reason for a dye to give a buff, either. I don't think it should have any kind of gameplay application.
Having super rare dyes with particle effects sounds like a fun something for the expansion pack or as rewards for true end-game content releases later on.
Yeah, my original idea was to have them drop at end-game Inferno as item drops. You could trade them like any other items, basically becoming one of the more valuable items in the game.
I just think Blizzard is too greedy and will release this more as a paid DLC. I agree with you, though. If it were added to end game content that would truly be amazing. I remember the IK set particle effects looking cool, and that's 15 years old. They could truly do some amazing things now. I don't understand why they haven't already done it unless, like you're saying, they're saving it for expansions.
