About 1 on 1 arena.

I'll give my two cents about 1 on 1 arena. I went to the official Guild Wars site and there stood that I should write on one of these forums for suggestions.
This game "Guild Wars" got one of the best PvP-systems out there. How about a 1 on 1 arena ?

For example:
1. I go to a "Guild Challenger" in a specific arena.
2. I invite the one I'd like to challenge and he/she accepts.
3. I invite spectators who would like to observe our match.
4. When all are ready, we start the match.

The playerboard could look like this for example:

-Board-
!! Players !!
* Player 1 ( red team )
* Player 2 ( blue team )

!! Spectators !!
* Spectator 1
* Spectator 2
* Spectator 3
* Spectator 4
* Spectator 5


I think that many players out there would like this too.
What do you think ?

Please don't whine, thank you.
