Lucian Dash is Broken

It's pretty stupid. Just a played game as Leo support, but my stuns were useless. When I got in a good position to stun him, all he'd have to do is dash away. The part that irritates me about this is... I'D GET MY STUN ON HIM. When I'd use my Zenith blade and he would dash, he would get his momentary root, but when I dashed to him as per my skill, I would just go to where he WAS as opposed to where he IS. If I used my Q stun, he'd just dash away and again, he'd be stunned, but at too a far a distance to do anything. Usually it led to him dashing under his turret while still being stunned, so its pretty unfair... because what's the point of a stun if he can still move to the safety of his turret?

I have not noticed this happen with any other dash/gap closer effects. For example,if I use my stuns on a Cait that uses her E, then she is going to get locked down in the spot where she was when my stun hit. Same thing happens for Graves, any champ riding a Thresh lantern, etc. They all get locked down at the spot the disable hits them at. If I Zenith blade somebody with a jump like Kata, I'll still go to the location they are jumping too... as opposed to the location where they jumped from. It's pretty unfair, and while we went on to win that game, the laning phase was ruined because I had to keep putting myself at risk without getting a reward for landing my stuns because he was able to just dash away. I know my stuns have a lower CD than his dash, but he'd just play super safe until it came off CD knowing he could just blow through my disables like they werent even happening.
