The thing is, if all you want is level, then nothing is really going to be entertaining. There is no max level in this game and the higher you go the longer it takes to level further. Like the folks in ESO who think that 10 hours of focused leveling to get an alt to level 50 is too boring, you will not be pleased with any suggestions other than an instant boost voucher. For some of us, levels are not the end all of the game. We do a variety of things and leveling is one of them (and sometimes it's just part of the other things we are doing). Is everything int he game 100% entertaining? No. There are days where I really don't want to tend to my crops. Or do a certain daily quest. But overall, I do things that I find interesting, and leveling to unlock new skills or higher skill levels is one of those things. I do it in moderation though, because there are so many other things to do. On the other hand, I'm not really interested in PvP, so being level 60+ with 500+ GS is not a priority for me, so YMMV. What I'm trying to say is that if all you care about is the end of the road, the road itself can be the most beautiful road in the world, you'll still complain about the journey.
