I want the curious animals as well, taking them out made it too easy. It was a test of skills to make sure you completed what ever task you had and either not aggro them or simply butchered them.

The game should not be easier just because some of the community feels is too challenging.

Besides as many said there could be triggers such as drawing your weapon out and that would scare them off or you could even /intimidate (emote) to have the same effect.
