Welcome to the club!
All posters above state their personal views which is good, because you can read and decide whether it is relevant to you. I hope you see that the above opinions differ according to PvE and PvP point of view.
Basically I agree with Wretchman's story except for the fact that there is not much to do after you beat the game (PvE). If you are only into PvE that could be the fact; if you also like PvP then you are busy for quite some more time

Even if you are only into PvE you still can have fun depending on what your goals are (like getting a super rare weapon -see below)
With respect to farming for gears: there is no need to farm for gear other than an esthetic one. You can easily get the best possible gear (stat wise) without grinding for gold. But if you like the looks, you got to work for it. It is your choice.
And that, the choice, is what I love about this game! Hope you get on board.
