@Chakra Thanks for the post. Dota 2 also uses a 32x32 grid resolution. One caveat is buildings will be units with circle collision. However, I can completely eliminate all default collision in Dota 2 by giving every unit the Phased attribute (Phase boots in Dota 2). So, I'm thinking I can manually create and continuously update the pathing map for every unit throughout the game. This would be a very powerful solution IMO.
