How about making team duel tournament draft just like the CTF and TDM ones or something quite similar to it? Pre-selected top-tier duel players as captains would pick their "team" consisting of 5 players overall.

We could use something like ESWC 2004 or Davis Cup system. To make it short its basically like this:
-whole match bo5
-each game bo3
-first team who wins 3 duel games (bo3), wins the whole match and advances further in the tournament.
-each player can be used only once

Moreover to mix things up, so that everyone could be happy about playing their best/beloved maps, I'd like to see a different map poll for each of the rounds (games). Example:

>> First round map pool: aero, toxicity, phrantic, hektik, t9
>> Second round map pool: ztn, t7, dm13, battleforged, dismemberment
>> Third round map pool: dm6, t4, ztn, aero, dm13

......etc.....

Pick, pick, drop, drop.

The idea is that every player in a team would have the opportunity to fit in a particular round where he feels the map pool suits him the best and thus we would actually see some non-popular maps played as well.

Let's make it happen. Lets dream together (c) Cooller.
