You're using the 'appeal to legacy' argument, which isn't much of an argument.They've always been call-shot so what's the deal? I've never played 'biker-bar anything counts' 8ball.
The only real argument against call shot (other than luck makes the game more exciting) is that it penalizes two-way shots in which the shooter can possibly pocket two or more object balls (shooter is forced to call only one ball to remain at the table). If that is the main argument against call shot, then why can't that same argument be applied to straight pool and 8-ball to make the games less 'nitty'? Surely there are many opportunities for two-way shots in those games.
