Styling shop, color dyes & aggregations are all "vanity" items and are not required to play the game, hence why they cost diamonds.
I disagree,
They cost diamonds because FA used it to generate diamond sales/revenue. It was a fair item to spend diamonds on before the ridiculous amount of diamonds were required to plus and stat the gear to the current acceptable level.
Following your theory, would it mean buying house energy is a vanity item also?
The game has changed, diamonds used to go a lot further then they do currently and allowing players to spend diamonds where they are needed more is a better customer service plan.
RoM is all designed around the ability to customize your toon. It's not vanity when you want to make your colors or gear a little different, they are after all an extension of the player behind the toon.
I wasn't asking for the Aggregates to be a gold item, but only the coloring of them.
It wouldn't be as necessary if the in game sets weren't so disgustingly ugly most of the time.
But I never mentioned Aggregates, I only mentioned the Stying Shop which is not a CS item. It's an in game function to customize colors only.
