Keep collision gone, I would not like having my path obscured by the moving forward rear end of a marmot again as it shouts at me "YOU SHALL NOT PASS!".

What else is missing in this game? Mobs that sight/sound link. Leves don't count, they're already pre-grouped in such a manner. FFXI had sheep that would go plow you over if it saw you attacking another sheep. Here you go attack a nanny and the other nannys would just make threatening motions, and the billy doesn't so much bat an eye.
