Lvl 43 is the highest on my server.
I'm very impressed with the amount of content and detail this game has. i've only seen a fraction of it, and most people will never see all of it.
Some of the coolest things I've seen yet:
I'm fishing the Canals in Stormwind for about five minutes when these kids run up and join me
And checkout the freakin giant outside of Booty Bay!!!
And you cant fish in high lvl areas like bootybay since Blizzard has removed all the fish on account of hackers using fishing bots or some crap. And I had just spent a gold on the expert fishing book. They say they will have it fixed by the next patch, but i'm pissed.
