plain and simple blizzard failed to incorporate a feature for people who are colour blind.
i have contacted a few G.Ms now and to be honest they are all tripping over each other one answered "yes we are aware of this situation" one replied "thank you for bringing this to our attention" one said "go download a mod" ? lol really?
simple answer to the BASIC programmers @ blizzard change the red-yellow-green lights to a simple letter R-Y-G then the game will be in align with the D.D.A.
im writing this post on behalf of my nephew who atm cannot do his archeology because he cant tell what colour the lights are on.
and before i get replied back with "go get a mod" why should he have to? he has a disability what blizzard SHOULD be addressing in order for the company to remain respectable.
