I'm interested in the possible ramifications of switching to a hex grid for combat within DnD5e. It seems to provide a better reflection of how being adjacent/surrounded etc works (there's always a "side" of a cell that you share with adjacent cells) and also how movement works (diagonals, again, being an awkward consequence of squares.)
I understand that DnD, across all editions, is designed with square grids in mind. For this reason there will be rules that require some massaging to make them work, and there might even be a few that need to be completely re-worked. Likely there are play elements that would come up differently too.
I'm hoping that there are people out there who have tried this, and/or combat-experienced rules-lawyers who would be familiar with the difficulties involved here, who's experience/expertise I might draw on to inform my own attempts. I don't want to open a debate or discussion so much as get an overview of what difficulties might arise and thereby how compatible a hex grid could be with 5th Edition.
Obviously analysis from experience would be ideal, though if there are specific rules that would obviously require significant revision I'd be interested to know about them even if people haven't tried it.
Would the above, with slight re-wording so it's not a description of a question, but rather just a question be considered off topic as it's not hard facts enough, or for some other reason? It seems kinda borderline to me.
