Small sample: this pairing has only 44 ranked matches in the current window, so its win rate will swing more than deep-sample pairings as new games come in.
Why this works
Trying to set up a gank with this duo feels awkward. Io wants to empower a core with Tether and Overcharge, but Chen is busy managing his own army and doesn't benefit much from being the Tether target. Their kits also overlap too much on the defensive side; both heroes offer big saves and sustain, which often leaves the team without enough lockdown or burst damage to secure kills. To be fair, we haven't seen this combination played very often, so maybe there's a style we're missing.
