Darius FINALLY getting some late game buffs, but can we do something about his pull now?

I'm really glad to see Darius getting some late game viability with his mana refund and resets on his ult on the PBE, it sucked having him in a bad spot where he was a really good lane bully, but drops off the second laning ends like an anvil off a cliff.

But now that he IS getting some attention, can we make his pull more... "fair" doesn't really convey it, but I can't think of a better term. The animation is very unintuitive on when you're locked into the pull, sometimes it seems like people are getting pulled even though they left the area of effect before he even fully extended his axe, much less actually pulled people, I can't tell you how many times I've seen people waste their escape move or even flash, only to be pulled all the way back to Darius despite being clear with a wide margin. Most other pull/push mechanics work fairly well in terms of intuitive results, dodge blitzgrabs and thresh hooks before they hit you and you're clear, you have until you collide with Alistar and Poppy before you get shoved, but Darius's pull REALLY doesn't make sense.
