My Opinion:

1. If you're that stupid to walk into their sword or lose to that strategy, then you simply need a better technique.
2. Agree. Cheating/hacking shouldn't be taken into consideration.
3. Unsure.
4. There are ways to counter players who have "lag/delay" but if it's at a point where it's impossible to attack, then its bad.
5. Be mature and have good sportsmanship is the way to go.
6. Disagree. Less talking more sparring. It's called a quick spar room for a reason.
7. If you're planning on going afk, why the hell join the queue in the first place? It wastes your opponents time and others who are waiting to spar.
