What they fail to mention is the fact that you can fight like 20 guys at a time though ... so factor that in when making your xp calculations.
The problem with this game is, it gets people hooked early for leveling at a certain pace since you can fight so many guys at once and so the early levels really whiz past...
Honestly I find this game no more grindy than any other for the most part.
Besides, and with all due respect OP ... you need to install the game and try it out yourself, because honestly, who cares what anyone says here about a game.
We can only state our personal opinions, what we hate, you might love, so overall this topic is a complete waste of board space.
Install the game, try it out and see if you like it.
