Actually, in proper EVO, you do try to give your opponent two wins. That's the point of it. If you want to play strategy use characters that reduce damage, while still giving your opponent a fair shake at beating them.
If you believe the point of EVO matches is to win, then you need to stop EVOing, because you've completely missed the point. The point is not to win. It's to level your characters and allow your opponent to level theirs. Pure and Simple.
No it doesn't "automatically" mean that. Stupid things happen. I've seen a 1 power character with the base 1 pillz steamroll a 7 power with 6 pillz. However you should out of fairness (yeah I know a word that seems to only appear in your vocabulary when it's convienient for you, I've seen your other posts complaining about
ELO, yet you claim in the same breath here it's ok to go all out to win at EVO. This concept escapes me.. anyway), allow your opponent an opportunity to make up that win.
As far as 3 maxxed out turning up. What 90% of the EVO players (Including myself) do, is to EVO the one character, and then allow the opponent the other 3 wins. If it happens on both sides, normal EVO rules apply. If 4 turn up on one side, I've seen it go where they just concede the match and allow the opponent 4 wins, and I've seen it go to an all out fight. There's no "rules" governing this aside from your own sense of fairness.
However, EVO matches aren't about winning or losing. If you pay attention to how many BP you get from a EVO match where you don't level a character, and how many you'd get from just winning a normal match, there's about a 10-15 point difference in favor of a normal match.
On average if I don't level a character, I get 10-15 points if I win.
If I lose I get 7-10 points.
In a standard match, I get 30 points for winning.
I get 3-4 points if I lose.
If you can't accept losing an EVO match, then you don't need to be playing them.
