Nothing u can do against (INSERT SKILL SHOT STUN/ROOT/SNARE/TAUNT HERE),
EXCEPT DODGE IT!
Thats the point of a skill shot, if you direct it correctly you will hit alot more. The same goes with Vieg stun if you place it correctly you will hit alot more. Its up to your opponent to out play your skill shot, predict it coming and take appropriate action to bait/dodge/walk around it.
The delay is going to break him, as it will now be nearly impossible to land his stun. Which then means you wont be landing W. For instance, how many times does a malz land his Q? maybe 1/5 against a person with the same skill level. Vieg is gunna be the same way if they add a delay.
If they do ad the delay then there needs to be an increase to the stun duration, OR a major increase in CD, I know they are decreasing it a little but its gunnad have to be huge to compensate for the delay.
They are supposed to be buffing vieg after taking out DFG, the only buff I see is Q being turned into a skill shot, and some small amounts of CD reductions. But then they go and make W and E have longer delays and reduce the Ratios of R. In the end the Nerfs out way the buffs.
