Earthshaker + Treant Protector

Why this works

Layering control with these two heroes seems powerful, but their kits can have some awkward overlap. Treant Protector’s Overgrowth is a great setup for Earthshaker's Echo Slam, holding everyone still for the follow-up. The issue is that Overgrowth roots enemies in place, so if they're already spread out, it doesn't help group them for a bigger slam. You get the lockdown, but you might not get the massive damage you want. Fissure can block enemies in for Overgrowth, but both heroes are essentially providing long-duration control, which can be redundant if your team lacks the damage to capitalize on it.

The game plan for this duo is straightforward: wait for Earthshaker to get his Blink Dagger, then find a fight to land the ultimate combo. When it works, it can win a mid-game teamfight decisively. The problem is that it's often a one-trick plan. If enemies build Black King Bars, have saves, or simply position well to avoid getting caught together, both heroes can feel underwhelming. After their initial spells are used, Earthshaker and Treant Protector are just two melee heroes who can be kited, and the team is left waiting for long cooldowns to try again.
