Can you make a place where will be at least 200 battle rooms and there will be an npc who will receive registration from us and he will tell me a number of room where we have to go to battle with other player? I think it will be better if you make this.
But if u use battle hall then some people cant battle private but if there is a tournament hall then ppl who didn't know about the tournament or new players can battle in private. Also if there is a tournament hall then none need to go to another city for only one battle of the tournament. And I said about NPC bc if there is a tournament hall without any NPC then it will be weird.
