Tournament feedback

As a tournament organizer I am interested in feedback about what players prefer in tournaments.

Do you like when armies/matchups are pre-selected or random?
Do you like having a 'dodge' to avoid playing a matchup?
Do you prefer bo3 or bo5?
Do you like having a loser bracket?
What maps do you like to see in tournaments? (1v1, 2v2)
Do you like having an ally randomly selected or choosing for yourself?
Do you like having allies/players separated by skill level/tiers?
Prefer group stage or starting straight to bracket?

I love the new Draw option for match ups that alan did today. You know whats coming and can prepare with your ally and no silly unlucky doubles possible.
Imo for tourneys that should give the best games, especially since we finally play NO REMATCH in cw and qm now.
If we follow the "draw tourney" like the current one from Alan we dont need the 'dodge' anymore.
Group stage bo3 and everything after bo5 is fine. Maybe finals bo7 for the hype.
If no group stage i like loser bracket to mix it up a bit. Id like to have both tourney formats (with and without groups) from time to time.
For maps everyone has his own opinion, but for 2v2s i would like to see Crossroads and Central Ithilien more.
Looking forward to next Valentines Cup and who will ask who for a dance ;)
