You're talking about old-school vs new school. There was a time when RPG's were all about the time-sink, but thats not how it works anymore in the 21st century. Every series is streamlining itself to fit more with the mainstream ideal, which is a focus on endgame content, and little focus on the levelling process. That is just how it is right now, an RPG is *not* what an RPG used to be.
All of those games you mentioned? Old as dirt. They are the best rpgs in the last 20 years or so, but they're not making much money anymore. Ppl are playing games like WoW, Skyrim/Oblivion, latest in those weird action rpg hybrids (like Mass Effect, KOTR), where it doesn't really take all that long to reach the end. At all. In fact, the latest generation of games can be sped through within a few days to a week max. No joke. That is just how it is right now. Sure I agree an RPG should be like what it used to be, but you need to accept the fact that the "RPG" has been changed and redefined. Its no longer about the levelling, its about the gear, the bosses, and the raids/dungeons.
Its a bit of a double edged sword. On one hand this has made RPG's a lot more mainstream and a lot more accessible. Because they are so viable now for widespread success, a lot of money is going into them whereas before it was a small niche industry that graced you with a new game once every....few years? Now there's RPG's out every few months it seems like, its quite a change of pace. At the same time RPG lovers from years past have come to find out that while RPG's are enjoying higher popularity and higher budgets, the mechanics are changing severely. As a result, the niche community has been divided between those that embrace the changes and those that hate them.
In the end, RPGs follow the money now...and the money says RPG's are better without the long grind. It sucks but it is what it is. At times I enjoy the focus on post-cap content, rather than the grind part. But there are also times I wish I could enjoy that long and adventurous quest to endgame, filled with lots of parties, dungeons, etc etc. Things change, RPGs are what they used to be and wont be for a long time. Might as well get used to it.
