I spent more time Hunter than any other abilities, but they all follow the exact same pattern. They're like a tug-of-war with the game itself: as levels begin to require more expertise, you learn more effective ways to train. As grindy as Runescape is, as long as you really feel as though you're roughly keeping up with the ever-lengthening EXP pub, and so long OSRS gold as you have a very clear target in sight, it's never too daunting.
But many abilities tack disappointingly early on. I know from experience that it just gets worse when abilities reach the 90s, in which a single degree can take dozens of hours of the same activity. The EXP pub keeps getting bigger but there is nothing new to do in sight, which is where leveling skills begins to get dull.
I found the crafting skills especially tedious. To train Herblore, for example, you withdraw stock after inventory of herbs and water out of your storage, then you simply watch your personality combine them. It's a slow process that never necessarily affects, because unlike putting different traps in Hunter, no matter what potion you are making, you're always doing the same thing.
Such skills are at their worst when you're losing money on the offer. They feel like another task you have to cheap RS gold pay for. Some other abilities, like Agility, feel incongruous. Agility enables you to access time-saving shortcuts round the Earth, but you train it by running circles round rote barrier courses. Agility is dynamic and beneficial in action, but training it is a chore that's completely divorced from what you actually use the ability for.
