The video that Necro linked clearly illustrates the issue, but I disagree with the solution proposed. In that video, the Tauren druid is standing a good 10 feet away from his target! You try swinging a hammer at someone ten feet away and see how often you hit!

I say don't extend the melee attack range on feral forms, reduce the melee attack range on everything else! ^_^

To the contrary, it's part of the issue with the range bug. The Druid Catform attacks are oriented differently than the orientation of the character itself, and in my experience auto-attacks and special attacks have different ranges. Calling it a "range bug" is really a misnomer because there are several things going on here that are bugs, and not just one.

I used the Shadowstep opponent as an example in the video, but the truth is that I can re-create this problem against any humanoid melee mob in the game (some beasts and dragons have such large hit boxes that it doesn't surface) by simply turning my kitty butt towards it and backing up. Eventually, my auto-attacks will fire despite facing away from it, but my specials simply will not. Simply put, the attack box for auto-attack damage is too far "back".

There are other bugs, such as very poor detection on "behind the mob", in a way that I've never seen on a Rogue but have consistently seen on Feral Druids. Very often, I'll Shred up my 5 points, hit either Rip or Ferocious Bite, and then have the game tell me that I am no longer behind my target for the next Shred, even if that target did not move. This is common on boss fights - again, even those with a hit box of absurd size and radius. So there are several things going wrong. The Shadowstep mob just helps to illustrate one of them.
