I find having a “main” in HS just dumb. It’s a habit people carried over from World of Warcraft, but it’s useful there because people there have to grind to even get a chance to complete.
PS I understand “learning a deck” is important but at the same time I find it hard to believe that requires the seclusion into one class exclusively,
e.g. I was able to turn very good with flood pala (my first Legend) but at the same time I could also learn swarm shaman relatively well.
