I'm not sure how to respond to this because as far as i know, no one has this expectation. I don't know who this is supposed to directed at.
Apparently I should've been clearer. I wasn't walking through enemy ink, I was walking over uncovered ground. Its a legitimate strategy but its not very fun. A mini map would make it necessary to do this a lot more often, thus making the game less fun.

You don't know who I could possibly be talking to and then in the very next sentence talk about how you huff it on foot specifically to avoid having your ink trail being spotted? C'mon.
And in what game is the entire stage not covered in one color of ink or another within the first minute? I don't think you have to worry about on screen maps making your walking over un-inked ground "strategy" more prevalent.
