1) WoW holds leading positions in terms of online players.
2) Many private servers are almost bug-free and have thousands of players online.
3) Mob grinding - I agree with this point.
4) Brand - not quite right, WoW has a rather complex PvP system (complex, of course, for those who are trying to learn), perhaps it would be appropriate to compare it to a car - anyone can drive it, but only after a long learning process can you drive it properly, and only after a long study of the basics with various guides + your own experiments can you drive it well.
5) Tomorrow, a Russian version of WoW will be released, which will be generally cheaper.
6) And yes, Lock, just because WoW is widely recognized and Warhammer is not, doesn't mean you should bash it.
Where do we end up when we save the world?
