Recently, the group has been talking about MEV again.

It seems everyone treats it as just "someone cutting in line to make a profit," but honestly, what’s affected isn’t a specific project, but the transaction prices and certainty for ordinary people’s exchanges and minting:
You think setting slippage makes it safe, but when the order gets reordered, you get squeezed first and then executed, and the fees are even higher…
The most annoying part is you have no idea which second you lost on.

Before major upgrades/maintenance on mainstream public chains, everyone starts guessing whether the ecosystem will move.
I think whether it moves or not is one thing; the more core fairness issue is how to constrain the ordering rules and the block producers, otherwise it’s the same wherever you go.
There are currently two heated factions in the community arguing, but I’ll stick to my habits:
Large orders should be split as much as possible, avoid chasing hot pools, and use private channels if available—at least prevent "cutting in line" from becoming the default tax.
