So Riot, let's talk about Veigar...

You removed DFG, lowered the ratio on his ult, and made his stun much harder to land in order to reduce the reliability of one-shotting someone from range. So reliability was the issue. I get that.

Veigar can still one-shot someone with his full combo if he farms enough with his improved Q, which is great. However here is the issue: his combo has almost NO reliability now. It is extremely easy to avoid his stun. Most other champions with hard-to-land CC that they need for their full combo have a way to make it easier to land that CC.

Let's look at some other champions that need hard CC for their combos, but have hard-to-land CC, but have a way to make it easier:

(1) Vel'Koz's knockup is hard to land, which he needs for his full combo to hit. Therefore, his Q was given a slow to chain into the knockup.

(2) Brand needs a stun to easily unload his full combo. However, his stun requires him to light you on fire and hit a skillshot. The 2 individual skills aren't hard to land, but landing them close together is harder, balancing him.

(3) Xerath has a hard-to-land long-ranged slow-moving stun, but he can AOE slow to make it easier to land.

(4) Anivia has a slow moving stun that she needs for her combo and to make enemies take more damage from her ult, but it has a large AOE and she can use her wall to lead people into the stun.

(5) Syndra has a stun for her full combo. However, she needs to set up her full combo in advance with many balls on the map. She can also slow her opponent before stunning them to make the stun easier to land.

I'm sure that there are more examples. However as you can see, all these champions have unreliable hard CC that is NEEDED for their full combo to land, but they have a way make their hard CC MORE reliable by another part of their kit; they have slows, they have walls, they have specific requirements that need to be met, you can see their combo coming but it's reliable, etc.

Veigar does not. He has a 0.5 second delayed easy-to-dodge stun. Now, I understand he can one-shot you. However, he can barely one-shot anyone without landing his Dark Matter, which is IMPOSSIBLE to land without hard CC, unless your opponents are terrible. He has no way to slow his enemy. He has no way to land his Dark Matter inside his cage either, since the AOE is small enough that they can simply sidestep the meteor.

So Riot, I understand removing the reliability off a one-shot champion, but can we please find another way that he can actually set up his combo? Add a slow to his Q, make his Dark Matter cast faster inside his Event Horizon, make his abilities stun if they hit an enemy inside Event Horizon, I don't know. Something. I don't want his instant stun back. I just want a way that I can actually set up his combo and burst someone. Let me interact with someone in an interesting way if I manage to trap them in my cage, because right now, all I can do is spam my Dark Matter and hope they are dumb enough to get hit by it in the cage.

Please, consider this RIot. Thank you. :)
