I really like the fact that Veigar is stronger & getting more popular
Not even kidding. It's what Riot wanted. For him to be healthy without an instant stun and be strong, hovering a 53% winrate in MID lane where he was meant to go. They managed to do it somehow. He has a higher winrate than old Veigar with DFG and was less popular.
Don't know why people are saying he'll get nerfed. If he gets nerfed, he becomes very weak as shown earlier this year.
Sincerely, a Veigar main since early season 3
