Changes i would like to see

Spectate System:-I would like to see a spectate system, at least for the tournaments. It's a good thing see the best players in a match and pay some attention to how they rotate, maybe you can learn few things there.

Matchmaking:-About matchmaking, in my opinion, the classes should be considered when building the teams. Sometimes one of the teams get 2 thiefs and 0 guardians, while the other one get 2 guardians and 0 thiefs, what can make some matches unbalanced

Build system:-I think GW2 should have a build management system, where you can save your pre-sets. That ables you to fast change builds and not be forced to relog to a different character with the same profession just to play another elite spec or core build. If I'm not wrong, we can get something near it but isn't a game feature, so, it's time to get a official one, it can't be that hard to do.

Thanks for your attention Devs, sorry for any english issue.
