Veigar, the misunderstood champion
You have all been there. Maybe around level 13 or 14. Few months into playing League and your hooked. Decide you want to play mid as an actual mid laner. Then you go face to face with a Veigar. "Oh, he's not to bad, really slow, small range, I can take him." 20 minutes in and he's 3 shoting you. It was there that I decided to pick up Veigar, and let me tell you, he is by far my favorite champ. Sure, competitive play wants people with more sustain, more early lane aggression. But I tell you, play him right and you can still win, even against a Ryze.
People just see Veigar at his base. He has piss poor movement speed, a auto attack which could be likened to throwing a cotton ball at someone, and the range of a disabled monkey. But look at his abilities. Every minion and monster kill he gets with his Q gives an extra point of AP. At max ranks, his Q's passive gives him an extra 5 AP per champ kill, not to mention that it scales 60% off of his AP. His W...100% scaling off of his AP. I have dropped ADC's to half health with just his W. E= the longest single stun in the game. Sure, at max range Ashe's arrow keeps them stunned longer, but that's only if it hits. Veigar stuns for 2.5 seconds every time he catches someone at max rank. And his ultimate, the bane of every APC in the game. 120% scaling plus does 80% of targets max AP in extra magic damage. Teemo's drop like a sack of rocks. His stun has great range, but that does take skill to land. His W may feel like a skill shot at first, but after landing the stun and pulling off that combo, it doesn't even feel like im trying. Some of my greatest games have been played on Veigar, and he deserves the love, even if he will never see the light of competitive play. So, if your looking for a new AP for the mid lane, try out Veigar. He's tricky at first, but if you get him down, he is so much fun.
