The problem I have with MMO end game is that for the most part they are all a grind for gear.
I enjoy the building and exploration of the leveling process.
The very words End Game instill feelings of going no where, doing nothing. It is what you do when the game has ended. To me this is what killed WoW and why I don't play it. The expansions focus too much on end game. And that amount to raising the level cap slightly, enough to need new gear, toss in a reworking(read shell game) of classes, skills and balancing, a few new dungeons, a few new raids...and now you are grinding for gear again. New expansion? Rinse and repeat. Once inawhile they toss in a new race or class.
But the focus(when boilded down) is almost always on grinding for gear.
To me that get extremly boring.
I think if MMOs focused near completly on end game being a PVP experience, they could build off of the OMP FPS craze. I think this is esp true if a MMO has plans of coming to a console next gen. But even PVP needs to be handled in a way that makes it more then just another way of grinding for gear. I can think of no examples on how to do it right at this point. I don't think anyone actualy has.
The best PVP MMOrpg I have ever played was M59. It launched in mid/late 90s, used a modified Doom engine, played fps style, had open world pvp, guilds with forts/halls, a huge(at the time) world, and most importantly a vastly different way of building each char. There where several classes of magic from dark arts to elemental to holy/healing to trickster and ofc weapon based skills. You had to work your skill to improve it. How well it worked was based on your stats.And there was no such thing as an atuoattack, and no one followed a routation script. Getting the picture? No cookie cutter cutout builds. No every person is the same exact thing as me. Factor in world wide chat(which took mana lol). And we had serverwide battles over guild hall takeovers. Invis players, fireballs, earthquakes, blindings, arrows, scimitars ... best ever PVP. Oh and if you died...you lost a whole level(and some skill imps/stats). Meaning that fighting was a bitch and it carried a lot of weight. No respawn points and carebear crap. You had a rare weapon? Great better not let a Faren Master shatter that thing in battle, because it would break, forever!
People talk about hardcore. That was hardcore. I loved it and I was damn good. Todays games...they are good. On paper they are amazing. But when you are one of millions of players, doing the samething, looking for the same exact gear sets...it all just feels watered down. ends up being boring. It is like being on a tourest tour of something compared to being able to experience it yourself. The MMO are just so ... standard. Almost scripted.
I think it is hard for me to play most MMOs anymore. They aren't bad games, and if that was all you knew...they could be great, I guess.
But end game? Meh'. End game is boring.
I like to build. I want more levels, more content, more classes, more races...just more. When I get to end game I start thinking about playing something else in most cases.
