For pve I kind of miss the dead zone. It made fighting a little more interesting.
Haven't tried pvp yet. My lower lvl hunters, parked at 19 and 29, had no problems killing. I even have a totally untwinked hunter (think he's only 28 - his only blue is a Chesterfall musket) who used to dominate in ab and wsg.
Anyway, I've seen how twinks have shifted in these areas from being rogue-dominated to being hunter-dominated. Now, it's going to be sick - hunters already did very well at these levels. The only thing I feared was a good warrior, keeping me clipped (had stone form and/or antivenom for rogues at 29).
I wonder if this "no dead zone" thing is going to last. I wonder if I'm going to find bg'ing challenging enough....
