Remember though guys this isn't a 1 to 1 port of the 5e ruleset. Its a game based on thee 5 E rules taking a pnp game and converting it into a 3D world.
If you want fully authentic there is tabletop simulator
I am curious, did you really read the whole post the OP wrote? He is literally proving that this change is just too much with too large consequences. Nobody on this forum want a 1:1 tabletop sim. For example they already changed Ranger class vs 5e ruleset and it's actually quite good. But with this backstab/higround change I wonder why they even bother implementing DnD at all. It's that big.
