Veigar needs some love.

With the increased stun duration, it is much harder to land your W now as a follow-up. I feel that if you do actually stun someone, your W's cast time should be reduced to 0.5 seconds instead of 1.25 seconds to ensure you can actually hit your opponent. So many times, even when I land my stun, my enemy just gets to walk out of my W because they bought merc treads. If you're going to make his stun so hard to hit, at least make it rewarding when I do hit it.
