Horrible proposal in every way - Stake,Burn,Stake,Burn is all we are asked to do lately.
The proposal does not address what happens when cards do finally unlock for sale/trade - Do we have to pay again?
Any long term players will have plenty of pre souldbound reward cards to use on land and the current soulbound cards are having no effect on the economy whatsoever.
Any new or recently joined players thinking of participating in land are thrown a new cost barrier by being unable to use the 'reward' cards they have been earning.
