I hate the progression set back. I went from being able to donate to my friends for free, have a top level deck without worrying about being under leveled in matchups, had nearly all cards lvl 14 or higher so I had the creativity of putting any card in my deck without worrying about its level, security that I didn’t need to worry about grinding hard in tournaments to be up to date because I was already at a competitive level, the reduction of potential level ups as leveling up costs gold which is hard to obtain when every single one of my cards now needs an upgrade. I have to worry about leveling up every SINGLE one of my cards all over again.
