How Templar Assassin and Io perform as teammates in Dota 2 7.41f, from ranked matches.
In Dota 2 7.41f, Templar Assassin and Io win 42.73% of ranked matches when playing on the same team, over 9,759 matches.
Seeing an Io tethered to a Templar Assassin appear on the map isn't as threatening as it sounds. Templar Assassin's strength comes from bursting a target from stealth with a clean Meld strike. Being attached to a glowing ally makes her much easier to spot, compromising her ability to set up these ambushes. While Io provides excellent sustain through Tether and Overcharge for heroes who want to stand and fight, this doesn't help TA's main defensive layer. Her Refraction charges will still get stripped by many small damage instances, and Io has no way to replenish them. The pairing feels clumsy because Io's support doesn't solve Templar Assassin's core problems.
