If you make laming no longer worth the risk, then you might as well not have laming. Advocating for making laming "more risky," is equivalent to making it not possible at all. Why would any smart player take a risk that is exceedingly not worth it when there already exists plenty of mechanisms to overcome it?
Why do you think this? There is room between it not being risky enough for the reward (as it is now) and it being so risky the reward is not worth it.
