@Jetah every person can't play every game, that's just a fact of life.
The feel of a game is part of what sets a game apart from every other game out there. For every game out there that someone can't play for one reason or another, there are a dozen that can be played, so there is no exclusion going on.
I'm handicapped myself. My particular handicap doesn't preclude me in this case. I am, however, practically completely blind in one eye, preventing me from playing many VR titles, and my knees can barely support me because of bone marrow density loss caused by being a renal patient, so I can't do too many physical activities anymore, even in something like the special olympics. (and I used to be quite active, mind you) but I have to face the facts that there are games I can't play, and games I can play at a disadvantage, that is just life.
Fractured is working really really hard to be as inclusive for various playstyles as possible, while keeping true to their vision of the final product. IF they sacrifice that vision, they become just another game on a list, with nothing to make it stand out really. This means that they need to hang on to those things they consider essential to the game they are working to create. They make compromises where they feel it doesn't actually make the game what they don't intend it to be, and right now, they have said that the movement schema and targeting system is something essential to their vision of their game. As is making it as hard as possible for people to run Macros/Bots in the game, although completely preventing such is impossible.
I'm sorry, if the game won't work for you with the schema they intend, however, that just means this may not be the game for you. Already they have set themselves a tough enough challenge trying to make solo'ists and group and PvPers and PvEers all happy in a single game on a single server. You can only ask of them so much.
