Poppy's Charge is still wonky

I've been playing Poppy for a while before taking her into Ranked, and after reaching her level 5 mastery, it's painfully obvious how unreliable Heroic Charge can be. While it was buffed in a hotfix and appended to the patch notes ( http://na.leagueoflegends.com/en/news/game-updates/patch/patch-524-notes ), which is welcomed. It has odd interactions with dashes; some dashes it seems to have no problem against like Zigg's Satchel because it is slow enough that Poppy can intercept him in his dash. But other dashes, like Lucian's Pursuit, potentially make Poppy miss her Charge entirely. I'm well aware dashes are supposed to be able to dodge Heroic Charge, but sometimes it just feels off, I don't know if this is intended.

The biggest problem I've encountered concerns the "carrying" part of the Charge. It seems that in certain instances, Poppy isn't carried with the enemy when charging, but rather, Poppy pushes the enemy away while staying at the point of collision, which makes it incredibly difficult to follow up with Hammer Shock. I'm not sure why it happens, I suspect it does when your target is moving in the direction of the charge. I don't think this should be happening; the description says that she should be carried with the target, which usually happens after her collision animation.

Here's an example: https://giant.gfycat.com/ImaginativeWarmheartedHartebeest.gif

Is this supposed to be normal?
