I've never made any kind of suggestion here before because I like the game and the way they have things setup for the most part. However, I've recently been encountering a recurring problem in the starting zones, like Razor Hill in Durotar.

I suggest we makes the NPCs do one of two things.
1) Make them immortal, perhaps with a special buff to make things easy.
2) Reduce their respawn timer down to almost nothing so we aren't left without quest givers/trainers/innkeepers for up to an hour (in some cases, if the griefer has no life).

If you disagree, let's talk about it. Maybe some middleground can be had.
