I disagree with that.
A distinction has to be made between hard-fought draws and so-called 'gm-draws'. It's an important distinction that the mere count of the number of draws is unable to make, which is why evaluating a tournament by only its draw percentage is an essentially flawed methodology imo.
Hard-fought draws have never been a problem in chess and never will be, unless you rule out a draw as a legal result.
All draws in Bilbao were the result of a fair and sometimes extenuating fight, and that's precisely because the scoring system encouraged the players to play for more.
In light of this I see the experiment as a success.
