How Treant Protector and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Treant Protector and Io win 48.78% of ranked matches when playing on the same team, over 1,921 matches.
Putting two global heroes together sounds like a clear path to victory, but their kits don't always mesh well. Both Treant Protector and Io often play as supports, which can make for a very passive laning stage that lacks kill threat. Their utility also overlaps; Living Armor provides global sustain, while Io's Tether does something similar for one target. This means you double down on defense without adding much offensive pressure. Io wants to empower a damage-dealing core, not another support. While a surprise Relocate to bring Treant in for an Overgrowth is a powerful play, it's a long cooldown combo that isn't enough to consistently secure an advantage.
