@Carter What are the bo3/BO1 results
In that poll (linked here ), the majority of the teams who experienced Bo1 by competing in elimination rounds at Worlds this year said they preferred Bo3 over Bo1.
Of the 192 teams who were asked, 57.3% voted for Bo3 (29.7% did not vote), and of the 135 teams who voted, 81.5% voted for Bo3. (Of the teams who had a preference, 88.7% chose Bo3.)
Even though Bo1 supporters (and those with no opinion) would be the most likely to skip voting, the poll clearly shows that of the teams who played in Bo1 matches at Worlds, more than half of them prefer Bo3.
