Saradomin sword is now part of the god wars dungeon, there is no reason to move it to the castle wars shop. Castle wars won't be changed to emps wars, it's a fully functioning minigame, it would be a waste of time to just change it back. You can still kill people much like back in the day with emps-wars, instead you get more tickets for it now than back then. The rewards aren't gonna be worth much in terms of straight up cash, however brawler gloves will save you a lot of time and or materials when skilling. The rewards are good enough, the minigame is good enough, I don't think it needs to be changed.
Also, this should be in the suggestion section, so i'm moving it.
