Seriously Dragon Is NOT WORTH LOSING OVER.
I've lost so many games now because everyone has this thought in their head that they absolutely need that horrible dragon that the enemy keeps dancing towards, when our team can't even fight the enemy evenly. REMEMBER GUYS: Sometimes it's OKAY to give up that objective. The dragon is NOT your nexus and letting the enemy have it when you cannot fight them without getting destroyed is almost always the right thing to do. Being able to survive a while longer to hope for some picks or towers to get you back into the game is a much better option than getting aced hoping to prevent a dragon, and then losing the game over it.
