Agreed Dave, a safe learning space for new players is essential.
I'm a bit worried that 10 wins isn't enough for them to get hooked before going to bronze.
I'd love to see Novice league get more competitive and last a bit longer, maybe even a small leaderboard for some bragging rights. (As long as it's too small a prize for a bot farm to buy spellbooks at scale just to farm it.)
