I agree with you and I hope that full realism mode will be like that, or at least similar to RO:O. But relaxed-realism mode will be in, and the minimap will be part of the game. That's just the way it is. Or not, if TWI likes my suggestion.
I guess some of you are fine with a minimap and think it perfectly fits RO. For reasons already shared, I disagree. We'll see what TWI does.
