I'm on a very highly populated pvp server. Back in the day it was one of the few servers that horde outnumbered alliance on (I happen to play horde), but I don't know what the population is like now. I suspect it's probably still skewed towards horde, honestly.

I avoided Tanaris since I knew that was a place where I'd run into lots of alliance. I went to feralas and hinterlands instead and leveled there. From there I've gone to felwood and the few quests I could find in azshara. I did sunken temple once and wasted some time in BRD before starting the plaguelands. I'm now getting close to finishing plagueland quests and I'm almost 57, one level until outlands. I did all this without RAF, so if you're using RAF it'll be even faster.

I thought I'd get stuck having to go to tanaris or all the way down to un'goro, but it turns out I have been able to skip those zones entirely. I don't think I'll be stepping foot in winterspring either.

I've been killed a couple times, but it's always been by a single ?? guy and they've never camped me. Overall, since I left the horrors of tarren mill - which will haunt me forever - I've been able to avoid almost all world pvp contact. My group is going to just be used for pve, so I'm completely cool with that.
