pvp servers are awesome

.....you'll come to find out. There are people on pvp servers that solo and don't join guilds....they quest alone until they either need help for a group quest or find out that they want to join a guild and the benefits of being in one.
I did that on my Night Elf Shadow Priest....I solo'ed my way up to level 70 then I joined a guild to get into Raids. Boo Horde suck....you probably made an undead Warlock.
