To be honest, I am not sure if this is a good move. This penalises players in the lower leagues, who were already substantially penalised by the recent changes in the chest rewards. Also, what is stopping the bots from creating accounts and buying/renting 1000 CP of cards to farm at Bronze 2? Going down this trend, will Bronze 2 players be targeted next? That's a scary thought, knowing how the game rules can be amended just like that and within a short span of time. Just my thoughts. Have penned down in greater detail here.
