Already did a thread about this and weapon coloring, but because we have weapon dyes now (yay), i can concentrate on this topic now.
We already have poses for the normal standing idle and some even for walking and running. Thats why i cant think of a reason why we shouldnt have custom poses while we have our weapon equipped. It shouldnt be that diffrent from normal poses i guess.
So for instance you could have a pose were you would hold a 2-handed weapon down besides you, or over your shoulder. Or 2 weapons behind your back or something, idk, enough possibilities here. It just looks a bit boring seeing the same pose over and over again, especially if you have a custom normal pose.
Oh, and please dont argue with realism here. Holding a 2-handed weapon over your shoulder is even more realistic then the stance we have atm imo. But this is fantasy and it doesnt have to make any sense.
