If they are wanting to change direction this is something for them to consider. Opening up a gap where players are disadvantaged if they don't read/understand so there is more sophistication for players to customize their playstyle, and more mystique overall.
They have been willing to go backwards with the dungeon design to where they don't explain the dungeon mechanics as clearly as, say, they did in Thaleia where you had those giant arrows saying where to go, and what to do, which was poorly received. Changing the rest of the game to not handhold as much would be a rather big step. It's hard to see it happening, but there have been statements (like the one at PAX) about changing things lately so we can hope.
