Yeah they need to add more variety to the combat and maybe create larger teams too.
I didn't know Quidditch wasn't going to be in that new Hogwarts game -- thats crazy! Maybe it's a historical thing? I don't know what time period Legacy takes place in but that sure is a surprise. Game looks great though, hopefully it lives up to the hype.
I feel like they will probably try to release a separate game that is all Quidditch like the did back in the day. Maybe make it F2P or something.
