At this point in the game, "rushing" is not a valid argument.

Here is the thing from my perspective people get called rushers because they jump into a game and concentrate 100% getting to max level then once they hit that and do everything to do with end game they jump onto the forums within a month of the game being launched and start crying about how little content there is for them to do.
I would think it would only be fair to point out that they refuse simple things like leveling another class or do some crafting or gathering . No they want more endgame content which they will do as fast as they possible can. Some rushers even plan for it. So they can stay up days at a time with hardly any sleep.

Yes i am pointing out an extreme case. some rushers only stay up 24 hours or just play 12 hours a day for a couple of weeks.

So if that isn't rushing.. what is?

There is plenty to do. If people don't want to level all of the classes/jobs/crafting/fishing/gathering etc fair enough but don't expect people to rush to agree with you when you have nothing to do.
There is lots to do in this game to last until SE add more content.

You mentioned 2 different types of people and confused them as one.

Someone who says "I want to focus on a single class, and do end game content." Is not a rusher. In fact, that's what A LOT of MMO players do. That doesn't make them rushers.

Someone who says "I want to focus on a single class, get hit to max level as fast as possible, and blow through the endgame content as fast as possible." IS a rusher.

They are 2 completely different types of people. Some people play MMOs for the endgame, that doesn't make you a rusher. Someone who rushes through all the content as fast as humanly possible IS a rusher. They are 2 completely different things.
