Blue Buff PSA
No, just because you're the midlaner doesn't mean you're entitled to blue.
No, just because I walk toward blue doesn't mean you should leave lane expecting to get it.
No, just because I smite blue so that you don't fucking steal it doesn't make me an asshole.
Yes, you are a dick if you steal blue if it spawns when I'm at base.
No, you still don't get to take blue as you please later in the game.
My camps are the same as your lane minions. They're my gold, they're my experience, and if I give you any of it then you damn well better say thank you. I never have a laner offer me a Cannon minion, so it shouldn't be expected for me to share my shit with you.
EDIT: Some people seem to be misunderstanding. If i'm playing Rengar, by all means I'll give you blue. If I'm playing a Jungler that is super mana-hungry, you can't have blue. The reason for this is that by giving you blue, I handicap myself and I trust myself to carry over a stranger I just met 10 minutes ago.
