That's kind of a silly argument. Sorry, but falling to your own assumptions is your own fault, when these assumptions were made too hastily.
The
argument is fine, since it's conditional on non-'realism' and 'fake difficulty' being non-desirable. The
conclusion may not hold, if either of the two is fine, at least some of the time - which, from previous discussions and general design patterns in the mod, seems to be the case.
*shrug* I mean, it's no skin off my nose. If the bots start to annoy me personally, I can just replace the chainsaws for myself. It's the newcomers who will have to live with "what you see is
not what you get", and will come back with this or a similar report next year, and the next, and the next...
Edit: In any case, if the chainsawbots remain as they are, at least a little explanation in the pedia wouldn't go amiss. Right now, I think they don't actually have a proper entry? The armour paperdoll has a, well, chainsaw that's pretty attached to the body. The chainsaw entry looks all in the world like a regular chainsaw, and you have to go to the nerdpedia to see that it's actually a retractable ninja chainsaw.

Or I could make consistent rules about how standard tiles (like walls) work...
From what Yankes said in the relevant OXCE thread, this likely is not enough. Asymmetric vision can also be caused by unit shapes, both player and enemy. It's like a lot of other weird bits in OXCE, it's close enough and you just learn to live with it (or make your own fork). Myself, I've never relied on getting to spot enemies just around a corner without someone in some manner actually not turning that corner.
