I think this thinking is a little flawed at times, because very few test match quality all rounders are involved in the game and in effect, you're picking a bits and pieces guy who doesn't do either role well enough to be selected as a specialist.Get him in the top 6, find an all rounder for 7. Think that makes them a stronger team.
It's like teams select guys and if they perform in either discipline it's considered a nice bonus - i.e if Mitchell Marsh either takes a couple of wickets, or hits a score higher than 20, it's considered a bonus rather than something they're selecting a player to do consistently.
I think what teams need to encourage more is the older days, where you weren't selecting a bit part all rounder to offer you some overs if your bowlers needed a break, because you had the Mark/Steve Waughs, the Borders, the Astle/McMillans, the Graeme Smiths who could give you some middling overs in test cricket when necessary.
That way you can go back to the six best batsmen and the four best bowlers, and if you happen to generate a Cairns/Kallis/Flintoff/Watson/Vettori then that's a nice bonus where you've got a guy who arguably can play on either facet, but it's not the reality for most line ups. The reason All Rounders are easily remembered is due to how few of them are actually honestly world class.
