Easy fix for Rarity Colours Backlash
I've mentioned this in a number of threads, but I'll raise it here... there is an easy fix for this Rarity Colours issue where everyone is happy.
Simply add an option in the Settings Menu for "Legacy Rarity Colours"
We know and understand why the new rarity colours are here... so have it off by default... but then simply have this option to turn legacy Colours on in the GUI menu, or above the Colour Blind area.
I severely doubt the perks/items icons are a stored individually as coloured image/textures, I imagine it's literally just the white image with a colour hash background that is modified dynamically on the fly... so I don't believe it would at all be a hard feature to implement, and it's such an easy win for all where everyone gets what they want.
While I'm not that bothered myself... (I kinda like the blue, especially on maps)... it's such an easy win for colour blindness, old hands at the game and content consistency, it seems a no brainer to add to me.
