I don't really understand why all the rules ends up reducing the rewards of skillful players that, through good usage of strategy, can achieve high rankings, while increasing the rewards of players that just bash through everything with ultra-expensive, high-leveled cards.
It's a game, after all: bad players should receive less rewards than good players. This rule will just increase the rewards of bad players that just bulldozer their way through the rankings with old, high-leveled expensive cards; and punish good players that can outsmart the opponents.
Well said, I feel the same way. Accounts shouldn't be punished for having more skill than another.
