Let your jungler kill scuttle
Unless they are across the map and you really need vision, there's no reason for you to steal it from them. You get 50 gold, he gets 80. You are removing 30 gold from the team. Additionally, they get HP to endure the hardships of the jungle. Not everyone gets a cushy little tower and minions to fight for them. Lastly, devourer stacks. Sure, 1 stack doesn't seem like much, but it adds up. Firstly, every time you take it, they lose that stack. So lets say 10 time in a game. That's 10 damage every auto attack. Assuming they have around 1.5 attack speed, that is a lot DPS they end up missing out late game.
randomly snipes my big chicken that's 30 less gold on the team.
