@tentative_noob First of all you are accusing players for colluding in Ranks , if you have proof please share it with wargaming and not just make baseless accusations in Forums.
I would like to point out, Both players are Great CV players, and any one can have a good and a bad game.
As far as Hiro Winning is concerned,
Hiro is a Unicum player with around 62 percent WR over all and is a super uncium CV player and Is able to Win his own Ranks with CV and even with Battle ships, so you are wrong to accuse him. Please go and check his Over All stats and it will prove what i am saying.
Look at his average performance in all games he played in ranks and you will realize you are wrong.
2ndly, correction : Striker is Clan Leader of Clan pn4vy and is not a Clan member member of hiro. And i dont think he will compromise his Star for anything like this.
Both belong to different Clans and you are wrong in saying co-operative Clan mates.
3rdly , in case your team won the game , would you accuse Hiro for letting Striker Win? So either way , any team wins you would accuse the other team player of collusion? whats this logic?
4ly, Hiro managed to be on top of his team , which shows he was most effective player againt your whole team, so tell me , did the rest also collude with Hiro and let him be this much effective?
