I've noticed a pattern where players' hitboxes (or whatever is used to calculate hits for AoE damage especially) get left behind at the original starting point of a dash, seemingly until the dash lands on the other side. This leads to a lot of frustration with Warden's CC range, walker slams, and so on. A great recorded example of this is in Mast's recent Seven video at 16:30 -- Seven throws a ball at Infernus who dives away but has ticks of damage follow him because the hits are registering at the old position
(I believe there's another decent example at 24:23)
