Hahahahhaha someone's salty about their last game.
Let's review your performance shall we?
In the last 13 GAMES you have played, you have double digit numbers for your death count.
Play safer, only trade when you know that you have the upper hand, you obviously did not abuse your advantage in lane (most mages can abuse Veigar pre-6, especially Syndra) and she can threaten a full 100-0 deletion with her ult just like Veigar. If he's broke, start playing him! I will throw my chips down that you will have AT LEAST 10 deaths in the game. He is very weak early on and is VERY easy to pick out and gank because he has low MS and no mobility at all.
