My first reaction when I see those "sure profit" arbitrage opportunities on the blockchain isn't excitement, but rather thinking: Am I just paying others transaction fees as a background board... Sandwich attacks are so real. You think you've grabbed the meat, but you're actually the bread being squeezed. Once slippage kicks in, you run faster than my mindset. Recently, the testnet incentives and points system are the same; everyone is guessing whether the mainnet will issue tokens, and they're already competing with each other over scripts. Honestly, everyone wants to be an early bird, but the early bird might also be bait.
