The question of whether Ethereum L2 fees are too strong is a complex one, as it depends on a variety of factors. From the existing answers, it appears that the fees may be high due to high usage. This could be because Ethereum's L2 solutions are becoming increasingly popular, as they provide a way to scale up the network and reduce transaction costs. On the other hand, it could also be because there is low usage of the network, which can lead to higher fees as there is less competition for the available resources. Ultimately, the strength of Ethereum L2 fees will depend on a variety of factors, including network usage, demand, and competition.
