Dear Mid Lane
When you see the enemy team takes Katarina, or LeBlanc, Zed, Akali, Talon, or pretty much any other super bursty assassin, instead of trying to pick a champion who is equally squishy and high risky / high reward, just take someone Like ChoGath or Swain and don't fudge up the lane for the first couple levels. Why risk having to outplay someone when you can just choose a champion who is far more difficult for them to kill and start cascading uncontrollably.
Your team will thank you for not gambling on a super squishy assassin where the lane will come down to who gets first blood. You'll also be immensely useful later as a late game threat because they won't be able to burst you.
Please and Thanks!
