What have the new, deadened bats accomplished in college baseball?

What was the point of them and what positives have they contributed to college baseball? Less injuries? A more realistic look for pro scouts on how players will perform with Major League bats? I mean what?

I think obviously the bats from the 90's needed to be adjusted, but what was wrong with the bats in the circa 2009 period? I remember that season and those prior producing a very entertaining baseball product. Now the games are typically rather boring IMO. I've watched less LSU baseball this year and last as a result than I once did.

So what, if anything, have they achieved that benefit the game?
