I usually dont rant, but if there is something i really dispise in WoW, it's cross realm zones (not cross realm raiding). Here's a bit why
Tried leveling a troll, and since troll and orcs start at the same place. Some questing areas in the start were so ridicously flooded with people tagging mobs, that i had to spend WAY to much time, just griefing my way through it. It ended up with me giving up the char and rolling another race. Because i just couldnt be arsed sitting in that bloody castle and waiting for that 1 guy to spawn, so i could tag him before the other 15 that were in there, and declining groupinvites i was trying to hand out.
And also, gathering proffesions, not even going to start on that.
and the rares, which others already said.
bleh, i get the idea and i like it. It's just the implementation of it that needed some more work, hopefully with a new patch or expansion they will come with CRZ 2.0.
