Draegan, mmo devs have to create tons of content anyways to keep players interested. It doesn't matter if it's during leveling or if it's endgame, the issue is the same.
The problem is they DO create all that midlevel content and then set the leveling speeds so fast that everyone passes most of it by and gets to an endgame where there is very little to do. Then to try and fix the lack of endgame content issue the devs create massive amounts of moronic, repetitive dailies. Wow that is sooo much fun
. Are you actually saying that the endgame of most mmo's is better than the leveling content? Get real. It should be but in actual fact it rarely is.
As I said before, devs either need to slow things down or get rid of levels altogether. What we have now (and you imply is so great) sucks the big kahuna.
