I mostly base my statement on tactical interfaces, and the knowledge that sighted players feel forced to switch to tactical (graphical) interfaces in order to compete.

Obviously blind players can add a make-shift tactical interface, by giving a specific status report when pressing a specific macro, but this will be slower than skimming a graphical interface.

I'm not sure if a system allowing two or three different voices to speak simultaneously would work to improve things.
