I don't buy the argument: "ETH fees was meant to be high!". Its the same as saying "ETH is meant to be unusable for people other than whales."
Isn’t a low number of transactions per second essentially built in to the original ETH spec? If so, surely it’s likely that each transaction should be expensive?
300% more is usually considered a good upgrade for most things (Apple is touting a whopping 20% speed increase on their latest iPad, for example). It's just that six years is a long time in this space and they've learned how to make things a lot faster since.
