Anyway I still feel Veigar will be just as viable as he is now. One thing not mentioned here about his Q change is that because it is a pass-through 1st hit effect he can choose to either get 2 ap from one Q or get 1 AP and poke enemy at the same time
Ahahaha-wait, you were serious. You honestly think that every time (or even 25% of the time) where Veigar goes for a Q, there's conveniently going to be another low-health minion or enemy champion right behind the first target?
Ahahaha-wait, you honestly think that Veigar can't damage minions to kill 2 of them with Q, it's not like his W is really good for softening up a bunch of minons, and yes ahaha it's probably impossible for enemy champions to be behind one of their minions, I swear Lux mid like never lands a Q on enemy champ after it hits a minion first.
Yes Veigar is changed but I don't think you should QQ as in team fights he is going to be so much more effective then he is now.
You're still missing the point. Let me simplify it for you.
WHILE IN LANE. YOU ARE NOT ALONE. THE ENEMY LANER MAY TRY TO HARASS, KILL, OR ZONE YOU. MINIONS WILL NOT ALWAYS BE PERFECTLY PLACED AND HARMED SUCH THAT YOU CAN Q TWO AT ONCE. YOU WILL NOT HAVE SUFFICIENT SPARE MANA TO W EVERY WAVE MULTIPLE TIMES. DOING SO WILL RESULT IN MISSING CS. THE ONLY POINT AT WHICH YOU CAN Q TWO MINIONS EVERY TIME IS WHEN YOU'RE FARMED ENOUGH TO ONE-SHOT THEM, AT WHICH POINT NONE OF THE ABOVE IS A CONCERN.
Also, as Jiokuy said, Lux Q has better range. And it still doesn't happen every time (or even all that often).
But your comment about "in team fights he is going to be so much more effective then he is now"... I'd laugh harder, but at this point it's honestly kind of sad that you're still pretending that you know what you're talking about. Think about what you're saying, bud. "A stun with a 0.75s delay and very visible particle effect beforehand is superior to the same stun going off instantly." Are you sure you want to argue that?
