During the times when I was playing well and effective, there was one strategy that gave me an unfair advantage. Before every battle, I would look at what the team was doing, in team games, and I would fill that role.
Nowadays, I'm not trying to read the battle before I engage. I do quite the opposite: I force a reaction out of the opponent. If I wish to always win, my best option is to never fight, and then watch as everyone chooses to do the best thing, never reacting.
Once again, the best option remains not to fight, but observe until someone fights. And I've stopped trying to fill that role. If all the previous reasons didn't make others believe a high winrate is impossible to cheat to get, how many reasons will be enough to prove it?
I'm a toxic, edgy player, I expect people to complain about me saying this in the comments! Because I'm fragile, I'm leaving until next week, and I won't read the comments until then.
