Actually this is a very good suggestion. If the toss is removed and the visiting team decides whether to bat first or bowl first, then there is no advantage for the home side to prepare sub-standard pitches. In such cases, we would no longer have dust bowls in which the spinners have unfair advantage. Teams such as South Africa and New Zealand would refrain from making pitches that give undue advantage to their pacers.
In the history of cricket home teams make pitches which favors their strength and if the visiting team has the prowess to challenge that then we saw great battles in Test cricket, Australian and England pitches were seeming pitches in the 70 s and the West Indies had some the worlds best fast bowlers and they started winning because of their bowling quality and had some legendary batsman, when Australia was dominating they had some world class fast bowlers and then a legendary spinner in Shane Warne and hence they dominated everywhere, even if India now prepares green pitches there is no way an visiting team will defeat them as India have some world class fast bowlers too as it is not the spinners than are winning matches for India in the past few years.Now coming back to the current match, both the Indian batsmen (Rahane and Rohit) look very confident today. Apart from Rabada, rest of the South African bowlers are looking teethless. The 4th wicket partnership is inching towards the 200 mark and if the Proteas want to give a fight, then they need to take some quick wickets now.
Rohit Sharma is in supreme form and he is scoring century after century for his lost days in Test cricket as this will be his best series in his Test career 
. Rahane is nearing his century and South Africa seems clueless on how to tackle the Indian players, there is no way South Africa is winning this match too as India is playing with three spinners and there is no inform batsman in their line up to challenge the Indian bowling line up.
