What's the point of a "grind to cap" anyway except to waste everyone's time?

Unless they have a purpose to the journey, there's really little point in the exercise if all good content is reserved for endgame players. Making 200 badly designed quests to pad out the levels is no good reason, unless those quests are actually fun and worth doing.

Quest-grind, EXP-grind, it's all just the same thing at the end of the day. Grind!

They might as well just do an EXP grind and spare themselves the effort of making hundreds of quests everyone will skim through anyway.
