fan - test - tournament "Goshan: Last One Standing..."

I don't know how the masses will react to this endeavor, but my personal opinion is that it's an overkill. Why so many tournaments? Each one has only 6-10 participants. Tournaments without a large number of strong players are no longer the same!

Yeah. On Battle.net, all new features were usually implemented using the following method:
1) Think it through carefully, test it against the computer
2) If step 1 goes smoothly, discuss it with the community, test it in fan games
3) If step 2 goes smoothly, introduce it in regular tournaments
4) If it doesn't drown in public criticism even after step 3, then it becomes a new standard.

A bunch of small tournaments is definitely not the way to go. Discuss it with the community, coordinate with the organizers of the main tournaments – and the new idea is tested in real conditions.
