Rare arrows my butt. 2 hours into the game on 11.11.11, I had 100 arrows. Go into ANY draugur dungeon and you'll walk out with 100 more arrows.
You can get tons of low grade arrows in this game, sure. LIke Steel, Iron, Nordic, etc, but finding loads and loads of glass, daedric, or ebony? Good luck with that.
I'm level 56 and I play an assassin/thief and barely use my bow and I only have 50ish daedric arrows. I used to use mainly dwarven arrows, but I've quickly used up those. Now I've given up on using high grade arrows and minaly use nordic/draugur arrows. And I don't even consider myself an archer. I can't even imagine how a primary archer class finds enough high quality arrows. They probably don't.
Granted arrows in general aren't in short supply, but the REALLY nice grades ARE. Perhaps it's not quite what everyone wanted, but it's a far cry of Oblivion where a couple dungeon runs later and you would have houses FULL of arrows.
