The brawl is so bad that my girlfriend may stop playing the game altogether. She's a very new player (2 weeks in) and just wanted to get her pack, but she kept running in to people playing tons of cards she doesn't have even close to access to yet, got her face punched in, it made her incredibly frustrated, and she's quit for now.
I suspect she'll be back eventually, but let this be a lesson for why "playground for very long term players with all the cards" can be very frustrating for new people.
