Veigar isn't going to be able to 100-0 a target without a passive like his. Getting a
severely weakens him in a 1v1, and any assassin is going to easily blow him up. Don't underestimate his damage, just because Veigar is 0/6 and you're a 7/0 Caitlyn doesn't mean veigar hasn't been farming and now has 100-300 stacks of his passive. He isn't going to kill you without his W, so dodging it inside of his stun will save your life. Also helps to know how cooldowns. If he upgrades his W second instead of his E, then dodging immediately after you're not stunned anymore will make you sidestep his W unless he does his Q and then W rather than EWQ. Upgrading E or W is based on preference though, so there's not really a real way to tell this. He's also pretty short range for a mage, basically a second Annie with equally terrifying stuns. If you want to learn to counter him then do this: Always be sure to dodge his W. When stunned, click to the side so you can sidestep an incoming q immediately. Decline as much cs as possible to him, and end the game before he's level 18 like you do with Vayne, Azir, Cassiopeia, etc.
