I am a big guy and I don't find any of the above problems. I don't love or hate it- it's not meant to have atmosphere like a baseball park, it's a multi use facility designed to host a variety of events most nights of the year. It's just OK, which is fine with me.
Plus, there really isn't a bad view in the house. I am a big guy too and the leg room in the upper bowl is not the best, but I don't find myself really uncomfortable or anything. It's not the recliner at home, but I am comfortable and the lower bowl seats are plenty comfortable. Seats in the balcony at Mellon were brutal for me as my knees would cramp up and hurt like heck from the lack of leg room. The noise at Mellon was better for sure and that place had it's quirks that made it fun, but Consol has great views of the ice and action. It is easy to get around and to exit, especially if you are willing to take the stairs. For a multi use building I think it is fine.
