Valve has disqualified a Dota 2 team from its upcoming The International 2018 for using a programmable gaming mouse. In doing so, Thunder Predator used an "unfair advantage", so says contest organiser FACEIT, during the South America qualifiers, which prevents them progressing to August's $15 million competition.

As reported by Motherboard, Thunder Predator's AtuuN is said to have selected Meepo—a Geomancer, who is billed as "one of the hardest carries in the game to play effectively due to his heavy reliance on micromanagement." Meepo can create clones of himself, and when each clone teleports, they deal damage in the surrounding area. And while this cloning method can be a powerful means of offence, said micromanagement means each clone must be instructed individually.

Under pressure—like, say, during a tournament—this routine isn't easy.

Motherboard links to this YouTube clip of AtuuN effortlessly directing Meepo clones around the map during the third game. This caught the attention of the Dota 2 subreddit, who in turn accused AtuuN of leveraging a software macro—a process that lets players roll complex button combos into fewer/single clicks.

Combat logs (see above) showed that AtuuN teleported Meepo clones at the exact same time. This process would normally take players several seconds—they'd otherwise need to instruct each Meepo individually—but Thunder Predator denied using macros. It did, however, concede that a programmable mouse may be at fault—a Razer Synapse 3.

"The player of our squadron ‘Atún’ has a Razer Synapse mouse, which, like any professional player, has put its own manual configuration to be able to have a better use of Hardware in benefit of its efficient performance in each of the games played with this hero (Meepo)," says Thunder Predator (via Google Translate) on its official Facebook page. "In this way, we highlight the fact that no type of hack has been used."

FACEIT, on the other hand, felt differently.

In the case of Thunder Gaming in SA Qualifiers, this is the decision that was taken:A) Disqualify Thunder Gaming for using unfair advantageB) SG vs Pain in the Winner’s FinalsC) Loser plays Torus in the Loser’s FinalsD) Winner of that Plays winner of A in the Grand FinalsJune 22, 2018

Thunder Predator suggests it's been hard done by. "That is why through this announcement," the Facebook post continues (again, via Google Translate), "we denounce this accusation, affirming that at no time, our player ‘Atún’ use any type of hack or particular program that facilitated his game mode before the match, yesterday, with the SG team."
