Nope, not at all. What I enjoy the most is actually terrible, terrible XP and generally favor I don't really need. Can't say why but for some reason the content and story behind it just tickles my fancy and I will run it every live and thoroughly.
There are things I will certainly grind for the XP and grind quickly at that but I don't enjoy that content at all. I grind it out as a means to an end, that end is pure XP not enjoyment.
It would be nice if the two intersected more often, sometimes it does though if I get a really good group in Wiz-King that is a fun time, I really like the story behind that but it's the only quest I can think of that I "like" that I "run fast" and that give "good" XP. The others are just purely a means to an end to get the stupid TR grind over faster.
