They are coming to those maps because some champs pretty much needs them. Lizard Elder and Hecarim for example.
And he needs that...why?
I'm honestly not sure where I'd even have room for that on Hecarim on HA.
X-flavor Boots (probably either Tabi or Ionic, maaaaybe boots 3), Randuin's, Cleaver, Maw of Malmortius, Zephyr (movepeed + tenacity + more CDR = yes please), Iceborne Gauntlet. There's a nice rounded-out build for tanky initiating Hecarim vs. just about any balanced-ish comp. If the enemy team has Teemo or Shaco or someone else who's giving you trap/stealth issues, maybe trade out the Zephyr for Lightbringer or something.
All the Elder Lizard really has going for it is cost effectiveness, which is nice if you're a jungler and don't have much gold going your way. On HA where everyone has insane gold generation pretty much regardless, it's a waste of a slot you could be using for a much more impactful item.
