I have played wow like 1 month now. First 20 levels are fun, but after it you have to run around to find quests, thats suxs. Also for ppl who arent good in english, quest logs arent clear enough to understand everytime, thottbot is good place but using it is boring Many ppl will disagree but its my opinition.
Positive thing is you are leveling you can do it when you want it, and leave when you want to.
In ko you always need good party to get good exp.
And in ko
-grinding exp isnt that bad, its fun with good ppl in party, also you dont have to think all the time where to go and read quests log etc.
Wow is great game, almost everything works
Ko is great game too, but k2 suxs. :P
