How Doom and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Doom and Io win 45.98% of ranked matches when playing on the same team, over 2,714 matches.
Relocating in to land a perfect Doom sounds strong, but the follow-through can be awkward. This strategy commits two heroes and a major ultimate to neutralizing a single enemy. The target suffering from Doom is already out of the fight, which means Io’s healing and speed boosts aren’t helping secure a kill that wasn't already guaranteed. Unlike a hard-hitting carry who Io could help pivot to another target, Doom lacks the instant damage to continue a rampage. After the initial gank, this leaves both him and the fragile Io exposed to the rest of the enemy team, who can easily turn the fight around.
