The hunting is just fine in 2g as long as you stay away from the the vast tracts of overbrowsed forests with no understory and very little food.
The hunting was just fine for the 11,700 hunters that harvested a deer in 2G in 2007, but it wasn't just fine for the 30,000 or 40,000 other hunters that didn't harvest a deer, because there weren't enough deer to support a larger sustainable harvest. Hunters can't harvest deer that aren't there no matter where they hunt or how hard they hunt.
