Levels 1-20 are dumb and mainly instanced.
After that it gets better..... I got from level 20 to 27 with 90% PvP and 10% mob hunting in roughly 5 hours of game time.
At this point you can see a major difference in people with skill and those without. HOWEVER it's so fucking easy that even the people without skill should be able to get good at this game in less than a month.
I think it will be the type of game that you can only get so good.... and I fear it won't take too much skill to be good.
I hope I am wrong
