All troll units in reforged are missing the heel toe. I know maybe this could be an artist choice based on the Zandalari models who barely have one( they are less proeminente) but Darkspear trolls are jungle trolls, they have a big third toe on their foot.
For some of you maybe this is unimportant, but this is for consistence, since in Wow they have,its not a valid retcon, this characteristic is what gives trolls identity, and make then unique among other races and other universes in general, it give tot hen an aspect more tribal more “primal”
here are the pics showing the difference from Warcraft 3 to Reforged:
