I don’t think it’ll change much for me. I’m boring - I sit my ass down, maybe run for a bathroom break at the half, and just watch the game. The sightline shouldn’t be much different. For my wife however, I think it will make a difference. She avoids the colder games for the most part and complains about the cold when she does come - so having the warm area to shuffle off to will probably result in her coming to more games which is a good thing.
I also don’t like the field club game day pricing for the new seats. We are lucky that it’s in our budget, but it’s going to make it harder to invite friends.
