Usually I have more nuanced polls. I intend to make a difference here for the sake of making good decisions for the future of 
- Rewarding Pack purchases and long term investment.
- Investors buying up Packs and dumping them after getting entries.
- Narrative engagement and marketing material.
- Resources sinks and a use case for Praetoria (Land).
- Playing with probabilities (for smaller investors).
I find Conflicts to be the best Airdrop mechanism I have seen in cryptosphere. I have been a part of HIVE since 2017 and I have been with Splinterlands through every step of its development. I have seen the problems of initial Airdrop systems (which were already superior to the industry average) get fixed with each iteration. I have only had one complain about Conflicts as a Dolphin sized player.
This was another Conflict that ended with no Cards Airdropped to me. The difficulty of getting a Card comes from the rarity. There were lower rarity Cards during previous iterations of the Airdrop mechanism. Although I have only gained a Zyrx the Emberglace from Conflicts I think the current system is perfect enough to be continued indefinitely. The reason will appear when looked at the game holistically as a part of a larger ecosystem.
Exclusive Cards, Loot Chests and Weekly Fortune Draw
As you can see, everyone gets to participate in some Draw where they can try out their luck while having minimum guaranteed rewards if they have enough entries. This brings variety to the ecosystem without overcrowding one system of distributing new Cards. This is why I think we should not try to fix what is not broken. I'm making this poll to see the community opinion. If you don't mind Conflicts be a regular unchanged system throughout the future releases, vote Yes. Vote No if you suggestions to improve the system.
