To do this on a per character basis is literally an attack on the veteran players of this game, as they are the only ones who would need to purchase this multiple times ie: players that have multiple raid buids / wvw builds / fractal builds / open world builds. Taxing your most loyal player base is not a good buisiness model. I could find this easier to swollow if it was account wide but per character is ridiculous and a slap in the face to the veterans.
