The first team to 2v2 world "Saranno Famosi" is a 2535 rating because they are win-trader, because the blizzard does nothing to prevent this?

Blizzard should realy (balance) Arena alot more , Team sellers - Boosters - Cheaters , aktion should be taken against those people.

They also need put more time into a system that is easy to spot cheaters etc like vieuwing the last 10 matches a team hsa played so you can see if they wintraded for their points.
