How Dragon Knight and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Dragon Knight and Io win 50.08% of ranked matches when playing on the same team, over 1,859 matches.
Tethering a Dragon Knight offers him much-needed mobility and sustain, which helps him stay on top of targets. The core issue, however, is that Dragon Knight lacks the high damage output to fully capitalize on what Io provides. Other cores can turn Io’s healing and Overcharge into rapid kills and a snowballing advantage. Dragon Knight mostly uses the support to be a slightly better frontliner and take towers more safely during Elder Dragon Form. A Relocate gank can secure a stun with Dragon Tail, but the follow-up damage is often too slow to be decisive. This pairing is functional, but doesn't create the kind of threat that defines a strong duo.
