The only reason this post has down votes is because mid mains wanting blue, no matter what.
I'm a jungle main, blue is not mid laners, it's a jungler. If I give it to mid, it's actually that, it's a GIFT. BE THANKFUL. However if I have a mid laner that demands blue, I will not give him it because I will not reward his poor attitude. If he is feeding, I will not give it to him. If i think it's just more useful on me atm, I'll not give it to him.
It is a GIFT. remember that mid laners.
That's why whenever I play mid, I will ask for blue, not demand it. I will not just stroll over and take it. And if I am given blue, I always thank my jungler.
