So I just noticed this. In case you were wondering why this post didn't get any traction, or even a preliminary vote, it is because there is not transaction ID of sending 100k DEC to @null (burning the DEC). That is the price to submit a formal proposal.

As for the idea itself, keep in mind Chaos Legion packs are not controlled by the DAO, and instead are owned by the company. Yabapmatt generally makes most economic decisions, and has chosen 0.05% deliberately. I'm not against raising that, but I would actually lean towards trusting Matt on this one. There are currently many other cards you can get as rewards to grow your account, and generally this is not a free-to-play game. I personally don't think something like this has a good chance of passing the votes.
