If color really matters so little
why not just have normal modes, heroic, mythic dropping epics while everything else drops blue/green or gives blue/green with the occasional epic? I mean if color really does not mean much to you and you just go for the upgrade... get your upgrade, if you do raids of a higher difficulty it just so happens to be a purple upgrade.
It seems to me that those who dont care, want everyone to not care or to feel bad for wanting something that is traditional in MMOs and RPGs in general. Whats wrong with having a type of item that is considered more rare, or tied to an aspect of the game that you may or may not do? Whats wrong with the prestige of purple that the Op and many like him seem to want? If color really didnt matter to you, but enough people seem to agree with the OP because.... THIS HAS BEEN TALKED ABOUT SINCE WOTLK (tbc had the pvp epics) Clearly a lot of people want what the OP wants.
to me the "too cool to care" crowd might secretly care. I mean why even argue against it if all you want are upgrades?
