Actually there was a lot of complaints about the one used in South Africa in 2010 because it was said to be "very unpredictable especially over a great distance", by many players. So maybe it doesn't apply to the Brazuca, and maybe the complaints are just anecdotal, but I wouldn't be so categorical about
Which only serves to further my point: by "innovating" when there was no particular need, Adidas created a f^%$ed up ball in 2010, which they then needed further innovation to fix. Pointless - but they sold a lot of balls. If FIFA had stuck with the traditional ball this whole time, that issue wouldn't have happened.
