I agree with the overall direction, however I think that maybe we're using a sledgehammer where the solution may require a greater degree of finesse.
Firstly, I think that DEC-B was one of the worst decisions we ever made. That option never should have been introduced to begin with in my opinion. Unfortunately, just saying or including the word "DEC-B" is enough for me to vote "no" on this, haha.
Secondly, I can appreciate wanting to solve the "voucher issue" as quickly as possible, but we really should take a breath to see if we can replace vouchers with a different incentive before removing them entirely. I understand the reasoning that anything we replace it with could theoretically compete with DEC no matter what we do...but I dunno. I think there ARE viable alternatives. It's something worth considering, since we are talking about incentives for two very critical aspects of our ecosystem: Staking SPS and owning Node Licenses. Playing fast and loose with those two fundamental building blocks is risky to say the least.
Short-term and Long-term considerations must be balanced equally. We can't sacrifice one for the other without shooting ourselves in the foot.
I see no reason we couldn't conceptualize a gamification of our DeFi products. That gamification could be based on "points" or "achievements" or whatever the heck we want. We don't have to limit ourselves to "tokens" and "digital assets". We can just as easily say "the more SPS you have Staked, the better your Liquidity Pool APRs". Unlock higher tier APRs by participating in Splinterlands DeFi. You can also say "buy more Node Licenses to unlock higher discounts on DAO proposals" or introduce discount tiers for transaction fees for bridging/buying...or whatever the heck DeFi benefits we can think of.
Bottom line: I think we COULD come up with cool DeFi incentives for those who are participating in the DeFi aspects of our ecosystem. And those incentives do NOT have to compete with DEC.
Once those new incentives are fleshed out, it will be a lot easier to transition away from Vouchers. Plus we don't have to mess with DEC-B! Just stop Voucher distribution, then let players spend the Vouchers like they normally do (until they run out of circulation), or perhaps jump-start the "voucher extinction" by offering players the option to somehow convert them into benefits within this new DeFi gamification system.
