It's an excellent idea because it makes the ranking spots between challenger level and tour level the most red hot in the whole ATP.
Qualies are bullshit in the first place.
nah seriously, it's reallt bad. you'd just end up with atp draws full of absolute cannon fodder.
I'd rather have Pere Riba off playing a clay court challenger somewhere than being forced to take a spot in a fast indoor tournament instead of a decent fast court player outside the top 100 like, say, Gilles Muller.
No idea what "qualies are bullshit" is even supposed to mean.
