Guild Wars 2

I think there are already a lot of topics talking about hot join problems.
Recently it is near impossible to end a match on the same team. Although this kind of match is intended to practice, it is near impossible to do so due to unbalance in the matches.
Some changes I suggest:
- If a player leaves a match, he is unable to join another for 5 min.
- Players no longer choose map or team. They just queue “practice arena” and are directed to a match when it is ready (a “ready” button is necessary so avoiding afk players).
- Someone joins team A only when other player also join team B, so keeping the teams with same number always.
- If someone leaves a match, other player on the queue automatically joins the match so keeping the same number of players on the teams.
- The system will keep populating the arenas with the players on the queue.

Please, put your suggestions to improve hot join/practice matches.
