Now please don't read this as me jumping all over your case here, because honestly I see both sides of this argument. I used to have a character with multiple 50 jobs and a craft or 2 near 50 back around the middle of last year. When they announced the 2.0 relaunch I deleted it and stopped playing for a bit. I pay and play now on my current character, but only a few times a week. My fear was that I would become one of the many people I see now with all their combat jobs at 50 and several crafting jobs at 50 as well. I often wonder what people like them do now when they log on besides the 2 primal fights or trying to cram another piece of materia into an already crowded piece of equipment. I think that, regardless of how many "new" things come out in the next few patches, it is still going to be some time before we get to a level of content in this game that exceeds anyones ability to master outside of a month or 2 of work. I mean, as it is now, with the right help, you could easily complete all there is to do in this game in a month or 2, with the exception of crafting. Hell, since SE isn't really concerned with banning botting accounts right now (and i understand why, believe me) you could cheat a little and probably knock out most of your crafting jobs in that time too. Or at least get them all to the high 30's.
The fact is, we are in a holding pattern until 2.0 drops. While I think there will be loads of new things to see or do once the new client finally drops, I think it will be sometime yet (2014 maybe) before this game gets to the same level FFXI was content wise after it had been released for the same amount of time. I think that anyone that has spent more than a few hours on it can see that being in a huge hurry to level everything right now is only going to mean that they will eventually run out of things to do.
Also, I think when people speak of adding more content to the game, what they really want is more jobs and an increased level cap. And we are still a long way out from that happening. I understand that we will get "jobs" next patch but, you won't be leveling them seperatly so what I am really refering to is more classes. I have been waiting for them to add muskateer to the game since the first time i stepped into the guild in LL. Also, with increased level caps ussually comes higher level instances and dungeons. We can only have 6 combat jobs for so long here before things start to feel stagnant to people. I understand WHY we are waiting, but that doesn't make it any easier :P Just my 2 cents.
