First of all, you don't even know how good the interactables are in MKX. None of you do. Which is why this thread is a joke. Secondly, we are coming from a game (Injustice) where the interactables played an even bigger roll than they will in MKX (NRS specifically said this). Nobody really complained about them too much once they were patched and balanced out in Injustice, so why fret about something which a) NRS now knows how to balance out now and b) NRS said they won't play as much as a factor as they did in Injustice. We already know they are blockable for God's sake.
Thirdly, your analogies are exaggerated, cartooney and your point is actually just completely wrong. Interactables isn't the equivalent being able to use their cheerleaders in the game or throw 3 balls at once or use their mascot to dance on the field while they are playing or whatever stupid analogy you want to throw in. C'mon man. And Sport's can't make physical alterations that change the competition's balance? Are you insane? Do you think playing on grass is the same as playing on turf? Do you think an outdoor stadium is the same as playing in an indoor stadium? Do you think one baseball field has a fence 302 feet from home plate is the same as another basbeball field that has a fence 436 feet from home plate? The Seattle Seahawks cruised to two straight Super Bowls because they got homefield advantage in the playoffs where the crowd noise is insane and the players can't hear eachother on the field so they have to use hand signals. The crowd is literally called "The 12th Man".
Teams can make whatever physical alterations they want to help get the advantage but in the end, both teams have to play the same game on the same field and they both have to deal with the conditions they are put in whether it was meant to be in their favor or ends up working against them. I ended up playing Forever King in Injustice in tournament on the 'dumpster' stage and while it played a roll it didn't determine the set. Learn to play the game and deal with your opponent before you start blaming your environment.
