Honestly I love HvZ, very fun and Interesting.
As hdin, it's all about anticipation, blind spotting, offscreen/ct stomping and being fast enough to avoid hits.
Imo, Smite foh is a thing but not such a big deal (especialy after wsg buff). Anyway it's ping dependant, rip.
Good matchup meNS.
Btw D2R wider screen may have a little impact on this match up, it will Be easier to avoid hits and to surprise zon offscreen jumps
