That recent swap just made me laugh and get angry at the same time: I thought I was steady by watching the router, but it turned out the slippage was "about right" + the pool depth was too shallow, and I placed the order twice by mistake. The second time, someone conveniently snatched a piece, and the transaction price was like slipping on a banana peel. Basically, the rhythm was terrible: when the market moves, it still confirms slowly, leaving enough time for MEV to perform. Now retail traders complaining that validators rely on sorting to make a living, I truly empathize... My review conclusion is simple and blunt: don't blindly trust low slippage, first look at the depth; if you can finish in one go, don't split; if you really want to split, minimize the time difference, or you're just paying others' wages. That's it for now, going back to continue cursing the sandwich.
