To me, it seems very obvious that any validator network NEEDS a permanent reward pool to incentivize the stability of the network.
However, validators usually pay in their own token - so I'm not sure why vouchers are needed instead of just "right-sizing" the SPS reward pool for validators going forward?
I DO agree with Cryptoeater that the current use-cases of vouchers are essentially just a reduction of DEC demand, while simultaneously complicating the experience for players that just want to buy things.
Going from Fiat -> Credits -> Buy Cards -> Sell/Burn Cards -> DEC -> TribalDex -> Vouchers is a frustrating experience...
(While there are other methods for experienced users, that is a typical flow for getting fiat into our tokens - and it's pretty bad for NPE.)
Your concern about Trust in the project and tokens is important. But Trust is a strange beast, when the very existence of a DAO that, on a supermajority SPS vote, can change ANY aspect of it's own white paper and any token of the related game, - this means that we must be prepared to accept some flexibility on what we are putting that Trust in.
(And I do feel your concern - I can sense that this type of change would shake the trust of validator owners in much the same way that the changes to ranked leagues shook the trust of players that committed resources in expectation of no fundamental changes to the Ranked status quo.)
What I'm finally coming to realize is that ultimately the real Trust we should realistically expect is that:
I look forward to having a new DAO structure and trust your ability to steward it.
