Reward amounts should allow a player who has put in a game console worth of money into Splinterlands to be able to EARN the ability to level up their cards.
Some people have the equivalent of a late model used Honda or a new Hyundai invested and are still barely earning anything lol
and that's the problem- I don't want to earn a bunch of money but I do want the chance to earn my way up the ladder and that's not possible for anything less than buying in at the gold level and even then it's tough
my guild doesn't charge anything and they are relatively ok with donating when you can. We have 2 whales that have really pushed us up the ranks, but we all manage our own decks and coordinate delegations with in the team - it works for me I don't have a lot time for the social side of guild participation
