More interaction between the commentators and/or another commentator with "very good" english knowledge preferably a native speaker. Who can help out when words are needed...instead of "öhm" "ehm"...
I think bashor's/squassel's/whatever's english isnt bad at all. Better than Mika's IMO.
I also think it was a great broadcast. The only complaint is that you shouldnt switch from car to car so fast. There were also several occasions where you switched although there were 2 or more cars fighting for a position. But everything else was very good.
