I don’t really see why it should be either or. The POOL pool should stay as is. It seems quite popular and gives people an opportunity to participate in lotteries by just holding POOL (even though the weekly rewards are quite small now).
Additionally, there is no way to further subsidize Sushiswap liquidity. I have looked into it. So, we should think of it like a bonus.
Let’s just focus on Uniswap liquidity since most people trade there anyway.
