London fork was about limiting ETH inflation rate and MEV. The inclusion of a mandatory base fee resulted in an increase of overall gas prices. Before the fork I was able to get ERC20 transactions confirmed for <10 gwei during off peak hours. Now you will be lucky to get a confirmation at 20 gwei regardless. ETH network fees have limited is functionality and adoption for the growing DeFi sector by pricing many projects out of the market from fees. The situation will only improve once Layer 2 and forked chain adoption grows, as those chains will certainly have more to offer standard users.
